d. 142^2

Answered by Steve
if the dimensions increase by a factor of 3, the area increases by a factor of 3^2, so A is correct.

13^2 * 3^2 = (13*3)^2 = 39^2

No, smh is wrong. It doesn’t change every day not even every month it stays the same, not forever. But, for a long time for example I‘ve seen a test stay the same for almost a decade now. ~you have got to be kidding me
