Answer:
Step-by-step explanation:
D is the answer
52s + 30b because 52 x s + 30 x b = 52s + 30b
By comparing the perimeters, we can deduce the scaling factor:

The areas scale with the square of the scaling factor, so the new area is

Parentheses first
9q-14+3q-3(8)=7
9q-14+3q-24=7
Combine like terms
9q + 3q - 14 - 24 = 7
12q -38=7
add 38 to both sides
12q - 38 + 38 = 7 + 38
12q = 45
divide both sides by 12
q = 45/12
q = 3.75
