the length of a rectangle is five times its width. if the perimeter of the rectangle is 96 ft, find its area.

romanna [79]

Answer:

lets say that the length is L and the width is W. With the given info, we can say that L=5W.

We know that the perimeter is all four sides added, so..

5W*4=20W

20W=96

W=4.8

L= 5*4.8=24

Area is equal to 24*4.8, which is 115.2

Voila! Your answer is 115.2 sq. ft!

o-na [289]

Answer:

$\large\boxed{5x(6x-x-2)}\\\\\boxed{-5(-6x^2+x+2)}\\\\\boxed{5(2x+1)(3x-2)}$

Step-by-step explanation:

$30x^2-5x-10=5(6x^2-x-2)=5(-1)(-6x^2+x+2)=-5(-6x^2+x+2)\\\\30x^2-5x-10=30x^2+15x-20x-10=15x(2x+1)-10(2x+1)\\\\=(2x+1)(15x-10)=(2x+1)(5)(3x-2)=5(2x-1)(3x-2)$
