Answer:
The perimeter of the rectangle is 17.70 feet
Step-by-step explanation:
- The perimeter of a rectangle is → P = 2l + 2w → where l is its length
and w is its width
- A rectangle has a length 15x and a width 2x³ + 4 - 2x²
- We need to find its perimeter when its length is 5 feet
∵ The length of the rectangle is 15x
∵ The length of the rectangle is 5 feet
- Equate the length's expressions
∴ 15x = 5
- Divide both sides by 15
∴
- Now lets find the width of the rectangle
∵ The width of the rectangle = 2x³ + 4 - 2x²
∵
- Substitute the value of x in the expression of the width
∴
∴
∴
∴ feet
∵ l = 5 feet and feet
∵ P = 2l + 2w
∴ P = 2(5) +
∴ P = 10 +
∴ P = 17.70 feet

Answer: a sperm and an egg
Step-by-step explanation:
<span>5x + 8y=16 -> y = -5 / 8 x +16 / 8 (2)
= -5 / 8 x + 2
use the slope to find the y intercept. Line is parallel so use m= -5 / 8
(-5 , 7) -> 7 = (-5 / 8 ) (-5) + b
7 = 25 / 8 + b -> 8 ( 7 = 25 / 8 + b)
56= 25 + 8b
56-25 = 8b
b= 31 / 8
so , y = -5 / 8 x + 31 /8.</span>
