Answer:
D) 16x^2 + 4x
Step-by-step explanation:
So a since there is two lengths and two height, you are gonna have to add them all up.
<u>5x^2 + 2x</u> + <u>5x^2 + 2x</u> + <u>3x^2</u> + <u>3x^2</u>
<u>(</u>See why I put the length value and width value twice? Because there is two of each.)
Now start adding up common factors. Let's start with any x^2
10x^2+2x + 2x + 6x^2
I added up the 5x^2 together to get 10x^2 and I added the 3x^2 together to get 6x^2, now you are gonna add those two up
16x^2 + 2x + 2x
(Just from looking at this, you can easily cross out answers A and B)
Now add the x together
16x + 4x
So the the answer is D
Answer:
$79.7
Step-by-step explanation:
Total income is $(234.8 + 64 + 20) = $318.8
Now, One-fourth of her income is budgeted for car insurance i.e. 
dollars.
And, 1/10 of her income is budgeted for gasoline i.e. 
dollars.
Finally, 2/5 of her income is budgeted for savings i.e. 
dollars.
Therefore, the remaining amount of her income = $(318.8 - 79.7 - 31.88 - 127.52) = $79.7 is left for her spending. (Answer)
Answer:
What is the height of each triangle side?
Step-by-step explanation:
Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
The smallest number would be 4
the three numbers would be 4, 10, and 14, which would have a sum of 28
