Answer:
let y% of 750 = 37.5
y = 3750/750
= 5
Answer:
Perimeter=2L+2w
P=2(x+1)+2(x-3)
P=2x+2+2x-6
P=4x-4
Area=Lxw
A=(x+1)x(x-3)
A=x^2-3x+x-3
A=x^2-2x-3
Step-by-step explanation:
I don't have one :v
The perimeter of the rectangle is 4x - 4 and the area is x^2 - 2x - 3.
The perimeter of a rectangle is calculated by the formula 2*(Length + Width). Hence, the perimeter for the rectangle in question will be 2*((x + 1) + (x - 3)) = 2*(2x - 2) = 4x - 4.
The area of a rectangle is calculated by the formula Length * Width. Therefore, the area for the rectangle equals (x + 1) * (x - 3) = x^2 - 3x + x - 3 = x^2 - 2x - 3.
