The perimeter of the rectangle is 14x + 4, the length of the rectangle is 2x. What is the width of the rectangle?

5x+2

Step-by-step explanation:

P=2L+2W

14x+4=2(2x)+2W

14x+4=4x+2W

14x+4-4x=2W

14x-4x+4=2W

10x+4=2W

(10x+4)/2=W

5x+2=W

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
