If the length of a rectangle is 1 meter more than three times the width, then write an equation for the perimeter of the rectangle in terms of the width of the rectangle.

The relation between the width and the length is: l = 3w + 1 --- (1)  Perimeter = 2w + 2l --- (2)  Put (1) in (2)  » Perimeter  = 2w + 2(3w+1)  » Perimeter = 2w + 6w + 2  Perimeter = 8w +2

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

x=5

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
