Answer:
n=4
Step-by-step explanation:
step 1: Simplify both sides of the equation.
4n−1=6n+8−8n+15
4n+−1=6n+8+−8n+15
4n−1=(6n+−8n)+(8+15)(Combine Like Terms)
4n−1=−2n+23
4n−1=−2n+23
Step 2: Add 2n to both sides.
4n−1+2n=−2n+23+2n
6n−1=23
Step 3: Add 1 to both sides.
6n−1+1=23+1
6n=24
Step 4: Divide both sides by 6.
6n/6=24/6
Answer:
21

Answer:
Length in feet = X - 80
Step-by-step explanation:
A = width x length
A/width = length
(x^2 -100x + 1600) /( x - 20) = length
(x - 20) (x - 80) / (x - 20) = length
x - 80 = length
x - 80 = length
