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.

Step-by-step explanation:
74+47=x(sum of two interior opposite angle is equal to the exterior angle formed)
121=x
What are the x intercepts and y intercept
the x intercepts would be the right and left number (-5.196,0) (5.196) usually most of times the x intercepts would have negative and positive same answers and they usually run vertically while they y intercepts is where the the x and y intercepts meet they usually meets in the y axis so that would be (0,5.4) that is my way of explaining it.

p. s x= 110
y=120
Step-by-step explanation:
Let's take the blank space between y° and 40° as n°. Then let's solve angle AFC, and remember x is given, 110°.
x°+ n°+ 50° = 180°
110°+50°+n°=180°
160°+n° =180°
n = 180° - 160°
n = 20°
Remember that angle y, angle 40° and angle n are on a straight line, which means they add up to 180°. So
y + n°+ 40°=180°
y +20° +40° = 180°
y+ 60° =180°
y = 180° - 60°
y = 120°

Step 1: –10 + 8x < 6x – 4
Step 2: –10 < –2x – 4
Step 3: –6 < –2x
Step 4: ________
What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
x < –3
x > –3
x < 3
x > 3
Answer:
The process of solving the inequality will be: -2(5 - 4x) < 6x - 4 8x - 10 < 6x - 4 -6 < -2x x > 3 This is in accordance to the rule of solving inequalities which states that whenever we multiply or divide by a negative number while solving an inequality, we must reverse the inequality sign.Which of the following equations has both -6 and 6 as possible values of c?

Answer:
3000 ft^2
Step-by-step explanation:
The top of the play ground
24 cm * 5ft/ 2cm = 60 ft
The side of the play ground
20 cm * 5ft /2cm = 50 ft
The area is
A = l * w = 60 ft * 50 ft = 3000 ft^2
Answer is 5, but i dont know how to solve it
Answer:Extract the formula for the height of a rectangular-based pyramid using your knowledge of algebra. H = V / (L x W) / 3. For instance, V = 60 cubic cm, L = 4 cm and W = 6 cm.
Step-by-step explanation:
CDEF is a parallelogram. Solve for x.
Answer:
x = 12
Step-by-step explanation:
24 = 3x - 12 (opposite sides of a parallelogram are equal)
24 + 12 = 3x
36 = 3x
36/3 = x
12 = x
Answer:
x=13
Step-by-step explanation:
The parallel sides on a parallelogram are equal, therefore you must find a number that would satisfy the requirement for equality in the sides' length
So lets get started by finding out what number would be 24 after 12 has been subtracted from it.
24+12=36
Now we need to find out how to get 36 from 3x
36/3=13
13.
x is 13.
Now lets check that our answer is right
13x3=36
so far so good.
36-12=24
That checks out.
24=24.

Find the interquartile range of the data.
84,75,90,87,99,91,85,88,76,92,94
IQR is shorthand for interquartile range
=========================================================
Explanation:
The original list is {84,75,90,87,99,91,85,88,76,92,94}
It sorts to {75,76,84,85,87,88,90,91,92,94,99}
Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.
After we determine the median is 88, we split the sorted data set as follows:
L = {75,76,84,85,87}
U = {90,91,92,94,99}
Everything in set L is below the median. L for lower.
Everything in set U is above the median. U for upper.
Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.
-------------
The median of set L is 84, so Q1 = 84
The median of set U is 92, so Q3 = 92
Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)
IQR = Q3 - Q1
IQR = 92 - 84
IQR = 8
The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.
Un capital de $10 000 se coloca a una tasa anual de interés compuesto del 6% durante 3 años. Determinar el interés generado Si la capitalización es una vez al año Si la capitalización es una vez al mes
Answer:
(a) $ 1191
(b) $ 1966.8
Step-by-step explanation:
Principal, P= $ 10000
Rate of interest, r = 6 % per year
time, t = 3 years = 36 months
(a) Interest per year
The amount is given by
[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{100} \right )^{3}\\\\A = 10000 \times 1.191\\\\A = 11910.2[/tex]
Interest is given by = $11910.2 - $10000 = $ 1910.6
(b) interest per month
The amount is given by
[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{1200} \right )^{36}\\\\A = 10000 \times 1.1967\\\\A = 11966.8[/tex]
Interest paid is = $ 11966.8 - $ 10000 = $ 1966.8

Answer:
Since -15/16 does not equal -16/15, the statement is verified/true.
Step-by-step explanation:
Plug in the numbers for the variable:
-3/4 ÷ 4/5 =/ 4/5 ÷ -3/4
Copy dot flip:
-3/4 × 5/4 =/ 4/5 × -4/3
Multiply numerators and denominators separately:
-3 × 5 / 4 × 4 =/ 4 × -4 / 5 × 3
-15 / 16 =/ -16/15
-15/16 =/ -16/15
-15/16 does not equal -16/15.

Answer:
89*
Step-by-step explanation:
To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).
To find that angle (let's call it x), we have to use an equation.
Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.
x + 53 + 36 = 180
x + 89 = 180
x = 91
Now to find m<1, we need to use the supplementary angles theorem.
Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.
x + m<1 = 180
91 + m<1 = 180
m<1 = 89
Hence, m<1 is 89*!
Hope this helped! <3
