The perimeter (distance around the shape) of a rectangle is 40 cm. The length is 14 cm.
Let x = width of the rectangle.

Ravi says he can find the width using the equation 2(x + 14) = 40.
Fran says she can find the width using the equation 2x + 28 = 40.

Answer the questions to solve the equations and to compare the steps and solutions.

3. Solve Ravi's equation, 2(x + 14) = 40, to find the width of the rectangle.

Respuesta :

Answer:

2(x +14) = 40 (use the distributive property)

2x + 28 = 40 (solve exactly like you did for Fran)

2x = 12

x = 6
