Answer 5

Reorder the terms:
8 + 4y^2 = 264

Solving
8 + 4y^2 = 264

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-8' to each side of the equation.
8 + -8 + 4y^2 = 264 + -8

Combine like terms: 8 + -8 = 0
0 + 4y^2 = 264 + -8
4y^2 = 264 + -8

Combine like terms: 264 + -8 = 256
4y^2 = 256

Divide each side by '4'.
y^2 = 64

Simplifying
y^2 = 64

Take the square root of each side:y = {-8, 8}

Answer 6

wow ur good u deserve medal and fan thx!

Answer 7

but what about -8

Answer 8

Answer 10

4y^2=256
y^2=256/4
y^2=64
y=8

Answer 11

that's all you need
