Arectangle is 4 times as long as it is wide. the perimeter of a rectangle is 50 cm. what are dimensions of the rectangle?

20x20x5x5

20/4= 5 (four times as long)

Making the width 5 on each side and the length 20 on each side, totaling 50

I hope this makes sense!

what is the graph

step-by-step explanation:

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)
