Check the picture below, notice those three quadrilaterals, bearing in mind that a square and rhombus both have equal sides all around.

Divide both sides of the inequality by 4

Move the constant to the right-hand side and change its sign

Calculate the difference

And we are done solving!!~
<span>The cost that a carpet cleaning company charges is directly proportional to the number of rooms cleaned. The cost is $22 for each room.</span>
Answer:
5unit
Step-by-step explanation: since area of rectangle = length*width
Here length is (x+2) and width is(2x+3)
(x+2)(2x+3)=91
On further solving
2x^2+75x-85=0
2x^2-10x+17x-85=0
2x(x-5)+17(x-5)=0
(2x+17)(x-5)=0
x=5unit
