The length of a rectangle is represented by 3x +4, and its width is represented by 2x + 1. The
perimeter of the rectangle is 25 units. Find the value of x.

Respuesta :

Answer: X=1.5

Step-by-step explanation:

Solution

Perimeter= 2(l+w)

25= 2( 3x+4 +2x+1)

25= 2(3x+2x+4+1)

25= 2(5x+5)

25= 10x+10

Now subtract 10 on both sides..

25-10= 10x+10-10

15=10x

Now divide 10 on both sides to get x

15/10= 10x/10

1.5=X
