Answer:
<u>The answer is x = -2</u>
Step-by-step explanation:
Let's solve for x the equation -3(x+5)=-9, this way:
-3 (x + 5) = - 9
-3x - 15 = -9 (Solving the parenthesis)
-3x = -9 + 15 (Adding 15 at both sides)
-3x = 6
x = 6/-3 (Dividing by -3 at both sides)
x = -2
<u>The answer is x = -2</u>
Answer : 7.5 ft
