Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft

Answer:
<h2>d=4</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
11=−d+15
Step 1: Flip the equation.
−d+15=11
Step 2: Subtract 15 from both sides.
−d+15−15=11−15
−d=−4
Step 3: Divide both sides by -1.
−d/−1=−4/−1
