Answer:
6 and 3
Step-by-step explanation:
6 · 3 = 18
6 + 3 = 9
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

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.

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

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: [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]

Answer:
A
Step-by-step explanation:
Math
===================================================
Work Shown:
If we want this figure to be a parallelogram, then the opposite sides EH and FG must be the same length.
Let's use that fact to solve for x.
EH = FG
17x-29 = 12x-8
17x-12x = -8+29
5x = 21
x = 21/5
x = 4.2; answer is choice A
------------
Extra info:
If x = 4.2, then,
EH = 17x-29 = 17*4.2-29 = 42.4FG = 12x-8 = 12*4.2-8 = 42.4Both EH and FG are 42.4 units long which helps confirm the answer.

Step-by-step explanation:
x+y=3
x=3-y
putting the value of x
in this
x²+y²=5
(3-y) ²+y²=5
9-6y+y²+y²=5
2y²-6y+9-5=0

2y(y-2)-2(y-2)=0
(2y-2) (y-2) =0
2y-2=0 or y-2=0
y=1 or y=2
so x=2 or 1

Answer:
[tex]x=4.02[/tex]
Step-by-step explanation:
The given triangle is a right triangle, this is indicated by the box around one of the angles, signifying that the angle is a (90) degree angle. Therefore, to solve this problem one must use trigonometric ratios. These ratios are used to describe the relationship between an angle and the sides in a right triangle.
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\\[/tex]
Bear in mind, the names of the sides of the triangle are relative to the angle that one uses to describe it in the triangle. Therefore the (opposite) and (adjacent) sides will change depending on the angle one chooses to look at it from.
In this case, one is given the length of the side opposite the given angle. One is asked to find the measure of the side adjacent to the angle. Therefore, it would make the most sense to use the tangent (tan) ratio.
[tex]tan(\theta)=\frac{opposite}{adjacent}[/tex]
Substitute,
[tex]tan(20)=\frac{9}{x}[/tex]
Manipulate the equation such that it is solved for (x),
[tex]x=\frac{9}{tan(20)}[/tex]

Find the area of each figure
Answer:
92
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
one rectangle in the middle, one triangle to the right, and one triangle on top.
these areas we can calculate very easily. and then we simply sum up all 3 of them and we have the answer.
it is clear, the area of a rectangle is length×width.
and the area of triangle is baseline×height/2.
where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
the rectangle
R = 10×6 = 60
the triangle to the right
T1 = (14-10)×6/2 = 12
the triangle on the top
T2 = 10×(10-6)/2 = 20
so, the total area is
60+12+20 = 92
The area of the given figure is 92.
This figure contained 3 sub-figures.
One rectangle in the middle, one triangle to the right, and one triangle on top.
The area of these areas we can calculate very easily. and then we ad all 3 of them and we have the answer.
What is the area of a rectangle?The area of a rectangle is,
[tex]A=length\times width.[/tex]
What is the area of triangle?The area of triangle is
[tex]A^*= \frac{1}{2} \times base\times height[/tex]
Where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
The area of rectangle
[tex]R =l\times w \\R=10\times 6 \\R= 60[/tex]
The triangle to the right
[tex]T_1 = (14-10)\times 6/2 = 12[/tex]
The triangle on the top
[tex]T_2 = 10\times (10-6)/2 = 20[/tex]
Therefore, the total area is,
60+12+20 = 92
Therefore the area of the given figure is 92.
