For this problem, let x be the width and y be the length of the rectangle. We use these variable to make an equation from the perimeter.
Perimeter = 2*Length + 2*WIdth
Perimeter = 2y + 2x
70 = 2y + 2x
The area of a rectangle is equal to the product of x and y. Since we want the equation in terms of x only, let's find y in terms of x.
y = 35 - x
Hence, the formula for area is:
Area = xy
Area = x(35 -x)
Area = 35x - x²
Answer:
The domain is all real numbers
-inf<x<inf
You dont have anything that we can answer to.
Answer:
x = 5
Step-by-step explanation:
The opposite sides of a rectangle are equal , then perimeter
2(- 2x - 6) + 2(4x + 4) = 16 ← distribute parenthesis and simplify left side
- 4x - 12 + 8x + 8 = 16
4x - 4 = 16 ( add 4 to both sides )
4x = 20 ( divide both sides by 4 )
x = 5
