Answer:
n + 7/5
Step-by-step explanation:
<u>Solve</u>
Let "n" be the varable.
Add 7 = +
Then, Divideby 5 = ÷
Therefore, the equation for this is n + 7 ÷ 5

Answer:
96cm^2
Step-by-step explanation:
Total surface area of a cube
= 6a^2
Given a = 4
Surface area = 6 (4)^2
= 6 x (4x4)
= 6 x 16
= 96cm^2
(2n + 5k)^2 = (2n + 5k)(2n + 5k)
Here we need to use FOIL
First - 2n * 2n = 4n^2
Outside - 2n * 5k = 10nk
Inside - 5k * 2n = 10nk
Last - 5k * 5k = 25k^2
That gives us 4n^2 + 10nk + 10nk + 25k^2, we can combine 10nk + 10nk to give 20nk, and a final equaion of 4n^2 + 20nk + 25k^2
