Answer:
A
Step-by-step explanation:
The easiest way to figure this out is to substitute in the variables. So for a, 2=-5+7 is correct, and 7=0+7 is correct as well. If you were to look at the other answers, you would see that the equation would not match up. Hope this helps!
We know that:
Area= length*width
Plug in the stuff you know.
35= length(tall)*5
Divide both sides by 5.
7= length
The photo is 7 inches tall.
I hope this helps!
