x=12.3

Combine the like terms (add the constants together and add the variables together)

The sum of the variables is 19x and the sum of the constants is -54

Add 54 to 180 and you'll get 234

Divide 234 by 19

The quotient is 12.31579

Round that to the nearest tenth and 12.3 is your answer

The length of a rectangle is four more than three times the width. If the perimeter of this rectangle is at least 70 square cent
ankoles [38]

Answer:

Step-by-step explanation:

Let L represent the length of the triangle.

Let W represent the width of the triangle.

The length of a rectangle is four more than three times the width. This means that

L = 3W + 4

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of this rectangle is at least 70 square centimeters, an inequality that can be solved to find the width of the rectangle is

2(L + W) ≥ 70

L + W ≥ 70/2

L + W ≥ 35
