Answer:
5
Step-by-step explanation:
a = 3; b = -2
a - b = 3 - (-2) = 3 + 2 = 5
First, let's multiply 86.50 by 20 since she deposited $86.50 each month for 20 months.
86.50 * 20 = $1,730
Now, we have to divide this by 24.50 * 20 to find how much out of her $1,730 that she used on singing lessons.
24.50 * 20 = $490
Subtract how much she used for singing lessons from her total amount.
1,730 - 490 = $1,240
Finally, we multiply the amount she has left by 1/4 to find out how much she spent on her summer camp. We can also do this by multiplying 1,240 by 0.25 since 0.25 = 1/4.
1,240 * 0.25 = $310
So, Molly spent $310.00 on her summer camp.

Answer:
A:
2(x + 2) + 2(2x - 5) =
2x + 4 + 4x - 10 =
6x - 6
perimeter = 6x - 6
B:
(x+2)(2x - 5) expand the brackets:
2x² - 5x + 4x - 10
area = 2x² - x - 10
C:
area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24
perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35
