Question

benji · Answer

C and D are addition and subtraction of 6 units, so probably not a shrink/stretch. So we are left with A and B, when you think of multiplying or dividing, which one do you think correlates with stretching, or getting bigger?

I don't really know what stretching is, I haven't studied it. But if it means it gets bigger then it would be multiplying, so A?
