<h2>Answer:</h2>

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × $\frac{1}{4}$ = 1

4 × $(-\frac{1}{2})$ = -2

Here is the simplified expression:

$12 + c - 2d$

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when so

Ierofanga [76]

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

$4 + 3 \sqrt{x - 8} = 34$

So, solving the eq.

Subtract 4 from both sides ,

$3 \sqrt{x - 8} = 30$

Divide 3 to both sides,

$\sqrt{x - 8} = 10$

Squaring both sides,

$x - 8 = 100$

Add 8 to both sides,

$x = 108$
