Surface area is square units, so you would need to square the scale factor.
The length was tripled, which means it is a scale factor of 3
3^2 = 9
The surface area would increase by a factor of 9.
The answer is B.
Answer:
y = mx + b
m = (-7 - -5) / (5 - 4) = -2
y = -2x + b
Use either point to find b
Using (4, -5):
-5 = (-2)(4) + b
-5 = -8 + b
b = 3
y = -2x + 3

Work from left to right
= -1 - 1.34 + 4.9 - 1.48
=-2.34 + 4.9 - 1.48
= 2.56 - 1.48
= 1.08 answer
