B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
A's area is 4x3=12, B=2x3=6, so yes, A is twice the area of B
a Answer: YES
b Answer: One side doubled, the other stayed the same, so area doubled.
The best approximation for sqrt 55 would be: B) 7 2/5
I got 3x + 2 = 5x - 4 which is a three-step equation. Does that answer your question?
Total area = 2*8.5*6 + 2*8.5*5.5 + 2*6*5.5 = 261,5 in^2 answer
