A rectangle has a perimeter of 38+x 38+x centimeters. The rectangle has a length of 3x−2 3x−2 centimeters and a width of x centimeters. What is the length of the rectangle? A. Substitute the dimensions of the rectangle info the perimeter formula P=2w+2l P=2w+2l b. Solve for x. C. Find the length of the rectangle.

The length of the rectangle is 6 centimeters

Step-by-step explanation:

The perimeter of a rectangle =

P = 2L + 2W

A rectangle has a perimeter of 38+x centimeters. The rectangle has a length of 3x−2 centimeters and a width of x centimeters.

Hence:

38 + x = 2(3x - 2) + 2(x)

38 + x = 6x - 4 + 2x

Collect like terms

38 + 4 = 6x + 2x - x

42 = 7x

x = 42/7

x = 6 centimeters

The length of the rectangle is 6 centimeters

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
