Answer: B
Step-by-step explanation: There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:
24x2+25x−47=(−8x−3)(ax−2)−53
You should then multiply (−8x−3) and (ax−2) using FOIL.
24x2+25x−47=−8ax2−3ax+16x+6−53
Then, reduce on the right side of the equation
24x2+25x−47=−8ax2−3ax+16x−47
Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and I do not recommend it for the actual SAT as it will waste too much time.
The final answer is B.

Answer:
The answer to your question is the letter D.
Step-by-step explanation:
Data
First rectangle Second rectangle
length = 3 length = 3
width = 2 width = 2 + 4 = 6
Process
1.- Calculate the Perimeter of the first rectangle
Perimeter = 2l + 2w
Perimeter = 2(3) + 2(2)
= 6 + 4
= 10
2.- Calculate the perimeter of the second rectangle
Perimeter = 2(3) + 2(6)
Perimeter = 6 + 12
Perimeter = 18
3.- Compare both perimeters
Perimeter 1 is smaller than Perimeter 2 by 8 units
