The dimensions of a rectangle are 3x+4 and 4x-1. What’s the polynomial expression that represents the perimeter of the rectangle in simplest terms?

2(3x+4)+2(4x-1)

Step-by-step explanation:

To find the expression that represents the perimeter you need to multiply each side length by 2 and add them together.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
