The answer is a.
5x-7 = 4x+4 solve for x
substitute x in (x-7) to get 11-7
3y-4 = 11-7 solve for y
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
if i help please give brainly
The lateral surface area of a cylinder is:
a=2πrh, we are told that r=1.8ft and h=4ft so
a=2π(1.8*4)
a=2π(7.2)
a=14.4π ft^2
a≈45.24 ft^2 (to nearest hundredth of a square foot)
The answer would be approximately 9 inches but the real number is 9.42 So B is the answer. I hope this helped ^^
