Whoever worded this question is a sadist, however this is what i think it was asking lol

A right triangle is half the size of a square. So if its area is 12, the square is 24. If our squares sides are 6. If that is true or triangles outer sides are 6 as well. To summarise:

Your square has an area of 24. Your triangle an area of 12, and their sides are 6.

Which expressions are equivalent to (7^-2)*(7^6)
Ierofanga [76]

Answer:

D

Step-by-step explanation:

(7^-2)*(7^6)=7^-2+6

......since the base 7 is the same, when u multiply them, you should add the exponents and keep 7 as it is. That will be 7^4, which in equivalent to ans D(7^2)^2.
