Answer:
B. 4m
Step-by-step explanation:
What you do is you just take the 8 and put it into the m.
m-8, 8-8=0 so A isn't your answer.
4m, 4(8)=32 so B is your answer.
B. 4m is your answer.
25x^2 - 64y^2
The first thing you can do is look for a subtraction sign. The word difference implies subtraction, so you can rule out any expressions that add terms. Secondly, you can look for squares. 17x^2 - 23y^2 is a subtraction expression, but 17 and 23 are not squares. However, 25x^2 - 64x^2 is a subtraction expression and its terms are squares. 25 = 5x5, 64 = 8x8. Hope this helps!
