Which graph represents the equation 12 = 32 + 4y? Explain how you know.

sergeinik [125]

What graph?
BTW the answer to that equation is: x=5
12=32+4y
12-12= 0 (cancels out)
32-12= 20
20 divided by 4= 5
Therefore, x=5

Solve by taking the square root of both sides. 3(x+4)^2-24=0

VARVARA [1.3K]

3(x+4)^2-24=0

3(x+4)^2 = 24

(x+4)^2 = 24/3

(x+4)^2 = 8

(x+4)² = (2√2)² ⇒ x+4 = 2√2 ⇒ x = 2√2 - 4
