User: 2x(7 + 2x)

Weegy: (2x^3)^4=(2X^3)^4 so this will be 16x^12

User: Simplify. (5 + 3)^2

User: 4 n^2 + m^2 n - 4 n^2 - mn^2

Weegy: 3-3 = 0

User: Simplify. 5x/x 20

Weegy: If 5x x > 100, then x is not 10 8 7 9 then X is 0. If you need more help try looking at this.

(5 + 3)^2

(5 + 3)(5 + 3)

25 + 15 + 15 + 9

= 25 + 30 + 9

= 55 + 9

= 64

4 n^2 + m^2 n - 4 n^2 - mn^2

= m^2n - mn^2

2x(7 + 2x) = 14x + 4x^2

andrewpallarca,
For (5 + 3)^2 you can do it in an easier way by completing the parenthesis firstly, your final answer is also correct though.
yeswey, thank you very much for that shortcut. I didn't realize that I can't do it that simple.
You are welcome!
