The perimeter of a rectangle is 304 cm. the length is 40 cm longer than the width. find the length and width.

Step-by-step explanation:

Perimeter = 2(length) + 2(width)

let x represent the width

this means that the width is 56cm

sub this into the length:

length = 56 + 40

= 96cm

answer: need picture of problem

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
