First one the answer is A; Alexander needs 70 ft
The answer is 12.
6+4 = 10
10 x 3 = 30
30 - 6 = 24
24 / 2 = 12
Step-by-step explanation:
First, apply the distributive property to the left side of the equation. Multiply each of the two numbers inside the parentheses by 12 and then combine those products. Next, solve as you would solve any two-step equation. To isolate \begin{align*}12x\end{align*} on the left side of the equation, add 24 from both sides.
