The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.

The area of the rectangle in terms of 'x' = 13x

Step-by-step explanation:

Using the perimeter formula to find the width w.

Dividing both sides by 2

as P = 30 cm

cm

Using the formula of the rectangle area

substitute w = 13 and l = x in the formula

Therefore, the area of the rectangle in terms of 'x' = 13x

for the points! : )

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
