1. 2(8x – 1) + 2(2x + 4)
2. 16x – 2 + 4x + 8
3. (20x + 6)
Step-by-step explanation:
The perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x + 6
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2( l + w)
Given the following parameters
length l = 8x - 1
width w = 2x + 4
Substitute the expressions for the length and width into the formula;
P = 2(8x - 1 + 2x + 4)
P = 2(10x + 3)
Distribute 2 over each term in the parenthesis
P = 2(10x) + 2(3)
P = 20x + 6
Hence the perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x + 6

Answer:
x - 17.95 = 71.80, $89.75
Step-by-step explanation:
Let the original price of the headphones be x
Amount of coupon = $17.95
You pay the final amount for the headphones after using the coupon = $71.80
So to find the original price of the headphones, the equation will be
x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75
