The length of a rectangle is 3 more inches than the width. find the length and width of the rectangle. the perimeter of the rectangle is 54 inches. write an equation that represents the situation. explain any variable used.

Width is 8 and the Length is 19.

Step-by-step explanation:

x = width

2x + 3 = length {length is 3 more than twice width}  

Perimeter of a rectangle is 2(width) + 2(length)  

2x + 2(2x + 3) = 54 {perimeter = 2(width) + 2(length)}

2x + 4x + 6 = 54 (used distributive property)

6x + 6 = 54 (combined like terms)

6x = 48 (subtracted 6 from both sides)

x = 8 (divided both sides by 6)

2x + 3 = 19 (substituted 8, in for x, into 2x + 3)

The width = 8 and length = 19

Best of luck,

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

-6 is the correct option from the above given options
