Answer:
w = 3
Step-by-step explanation:
8 • (w + 2) - 40 = 0
Pulling out like terms :
3.1 Pull out like factors :
8w - 24 = 8 • (w - 3)
Equation at the end of step 3 :
8 • (w - 3) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 8 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : w-3 = 0
Add 3 to both sides of the equation :
w = 3
One solution was found :
w = 3

Answer:
x = 4
Step-by-step explanation:
x + 4(x+5) = 40 (Given)
x + 4x + 20 = 40 (Distribute the 4 into the x and 5)
5x + 20 = 40 (Add like terms)
5x = 20 (Subtract 20 on both sides)
x = 4 (Divide 5 on both sides)
The answer would be 28 feet, to get area you do length times width, 7 x 4 = 28
