Question

Plz I need help with this ASAP

Answer 1

Answer:

x = 8

Explanation:

$\frac{3x^2}{4} =48$

multiply both sides by 4: $3x^2=192$

divide both sides by 3: $x^2=64$

take the square root:

$\sqrt{x^2} = \sqrt{64} \\x=8$

Answer 2

3x^2 / 4 = 48

Multiply both sides by 4 to get rid of the four on the left.

3x^2 = 192

Divide both sides by 3

x^2 = 64

The square root 64 to get x

Remember there are two answers

x = 8 and x = -8
