Priscilla is making gift boxes for her cookies. The total area of the box's base must be square foot. If the length of one side of the box is 4 foot, how long is the width of the box?

Area  = 16 ft^2

Width = 4ft

Step-by-step explanation:

Square means all sides are the same length. (Definition of square)

If the length is 4 feet, then the width is 4 ft as well.

Width = 4 ft

Length x width = area

4ft x 4ft = 16 ft^2 (area)

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)
