A rectangle has sides measuring (2x + 7) units and (5x + 9) units.
Part A: What is the expression that represents the area of the rectangle? Show your work.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Answer:
Part A:
(2x+7)(5x+9)
(2x*5x)+(2x*9)+(7*5x)+(7*9)
10x^2+18x+35x+63
10x^2+53x+63
Part B:
The polynomial has two terms, so is a binomial; also, the polynomial only has one variable, x, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a binomial of degree 2.
Part C: Part A demonstrates the closure property for polynomials because after multiplying the polynomials we obtained another polynomial.

Answer:
see below (2nd graph)
Step-by-step explanation:
It can be useful to consider the value of f(4).
f(4) = 1/2√4 -1 = 1/2(2) -1 = 1 -1 = 0
This matches the 2nd graph best.

4.5+n is it rational or irrational
Answer:
4.5 is a rational number, as it can be represented as 9/2. Many important numbers in mathematics, however, are irrational, and cannot be written as ratios.

The product of two and the difference of a number and three
Answer:
Step-by-step explanation:
Let ‘x’ be the number
So; the difference of a number and three implies; 3 - x
Therefore, the expression is;
2 (3 - x) or (3 - x) * 2

combine like terms, x-3+6
Answer:
x - 9
Step-by-step explanation:
That should be it, and let me know if I'm wrong. x is by itself and if you were to add 3 and 6 you'd get 9. So x - 9
Which equation of the line passes through the point (0,4) and is perpendicular to the lines whose equation is y=-1/2x + 3
Answer:
y = 2x+4
Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

If base of parellogram is 12 cm lenght is 8cm and prependecular diatance beetween two bases is 7cm find its area and perimeter
Answer:
84 cm^2
10 cm
Step-by-step explanation:
A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length
Area = base x height
12 x 7 = 84 cm^2
Perimeter = 1/2 x ( base + length)
1/2 x (12 + 8) = 10 cm
Anyone know how to do this
Answer:
9 sqrt(2) /2 = PQ
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = PQ = 9
9 sin 45 = PQ
9 sqrt(2) /2 = PQ
Answer:
7.7 cm
Step-by-step explanation:
You need to use trig ratios
this one needs the sin as we been to find the opposite side with the hypontenuse
9 x sin(45) = PQ = 7.65813172081
PQ = 7.7

Answer:
[tex]\$128.43[/tex]
Step-by-step explanation:
Since the cost for border paper is given in terms of feet and the dimensions of the gym are given in meters, we want to convert them to the same unit. Let's choose to convert feet to meters since that would be only one conversion:
[tex]15\:\mathrm{ft}=4.572\:\mathrm{m}[/tex]
Therefore, the cost of border paper is $6.99 pet 15 feet or $6.99 pet 4.572 meters.
Since the gym is rectangular, the gym's perimeter is equal to:
[tex]p=15+27+15+27,\\p=2(15)+2(27)=84\:\mathrm{m}[/tex]
Therefore, the cost of the total border paper for the gym is equal to:
[tex]\text{cost}=\frac{84}{4.572}\cdot 6.99\approx \boxed{\$128.43}[/tex]

The triangles at the right are similar. What is the ratio (larger to smaller ) of the perimeters ?
Answer:
The perimeters are in the same ratio as the corresponding sides.
Step-by-step explanation:
There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say, 7:4 (or 7/4). Then the perimeters are in the same ratio, 7:4.
Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

The three sides lengths of four triangles are given. Which triangle is a right triangle?
A- Triangle 2: 8,15,17
B-Triangle 3: 15, 16, 23
C- Triangle 1: 10, √65, 14
D- Triangle 4: 9, √260, 19
9514 1404 393
Answer:
A- Triangle 2: {8, 15, 17}
Step-by-step explanation:
You may recognize that the triple of choice A is a Pythagorean triple, so can be the side lengths of a right triangle.
Checking the numbers can be done nicely by a graphing calculator or spreadsheet to help avoid the tedium of doing it "by hand".
The basic idea is that the triangle will be a right triangle if the sum of the squares of the shorter sides is the square of the longer side.

Show that triangle FUN is isosceles.
an isosceles triangle is a triangle that has two sides of equal length
FU = 7 units
UN = 5 units
FN = 7 units
FU = FN
FU ≠ UN
FN ≠ UN
FUN is an isosceles triangle.
Please Convert 21/44
Answer:
Converted into Decimal Form : 0.47727272727
Step-by-step explanation:
To convert a fraction to a decimal you take the numerator (the number in the top of the fraction) and divide that by the denominator (the number in the bottom of the fraction.)
21 ÷ 44 = 0.47727272727
This is how you convert a fraction to a decimal. When you convert a decimal to a fraction it gets a little more complicated. Another way you could change a fraction could be by simplifying. Simplifying is when you make the fraction look more simple by decreasing the values of the numerator and denominator, dividing by the same number on both the top and bottom. If you are confused and want more detail, please comment down below.
Answer:
0.477272727........
Because 21÷44= 0.477272727..........
Given m
|| n, find the value of x.
m
n
126°
(8x+6)
Answer:
6
Step-by-step explanation:
since m is parallel to n, they both also have the same angles at the intersection with the crossing line.
the total angle on one side of a line is simply a half circle = 180 degrees (the angle of flipping over from laying flat in one direction of the line to laying flat in the other direction of the line).
so, the two angles of m with the intersecting line are
126 degrees and
(8x + 6) degrees.
and their sun must be 180.
126 + (8x+6) = 180
132 + 8x = 180
8x = 48
x = 6
Solve for 44.

44/42
58°
Answer:
answer below
Step-by-step explanation:
angles of a Tringle Addup to 180
let <2=x
61+58+x=180
x=180-61-58
x= 61°
now we know that the triangle was an isocelies triangle
<2=61°
But <2 and <4are on a straight line
therefore the sum of the angles are 180
<2+<4=180°
61°+<4=180°
<4=180°-61°
<4=119°
Write an equation that you can use to solve for x. Enter your answer in the box.
Answer:
x+63 = 90
Step-by-step explanation:
x and 63 add to a right angle so their sum is 90
x+63 = 90
We can solve
x = 90-63
x = 27
A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50 angle of elevation. His eyes are 5 feet above the ground. Using cos 50 0.64, what is the height of the tree to the nearest foot? 350 5 ft 20 Ft 24 feet 29 feet 36 feet 31 feet Done
Answer:
29 ft
Step-by-step explanation:
We solve using the Trigonometric function of Tangent
tan θ = h - 5/20
θ = 50°
Hence
tan 50 = h - 5/20 feet
Cross Multiply
tan 50 × 20 feet = h - 5
23.8350718518842 + 5= h
h = 28.8350718518842
h = 29 ft

Answer: [tex]2\sqrt{2}[/tex]
=====================================
Explanation:
Let's say we replace every copy of [tex]\sqrt{2}[/tex] with x
Doing so means we have the expression 5x-3x. That simplifies to 2x.
The last thing to do is replace the x with [tex]\sqrt{2}[/tex] and that's how we end up with [tex]2\sqrt{2}[/tex] as the final answer.
----------
In short: we subtract the numbers out front, and then tack on a root 2 at the end.
As another example, [tex]19\sqrt{2}-11\sqrt{2} = (19-11)\sqrt{2} = 8\sqrt{2}[/tex]
This is basically the same as saying 19x-11x = (19-11)x = 8x where [tex]x = \sqrt{2}[/tex]
The midpoint of AB is M(6, 3) . If the coordinates of A are (7, 4) , what are the coordinates of B?
Answer:
