Answer:

When 3x/4 - 13 = -9, x² = 256/9.

Step-by-step explanation:

3x/4 - 13 = -9

Multiply the expression by 4.

3x - 52 = -36

Add 52 to both sides.

3x = 16

Divide both sides by 3.

x = 16/3

Knowing x, let's square it.

(16/3)²

Apply the power to fraction rule.

16²/3²

Evaluate the powers.

256/9.
