Margaret is wrapping a box. The box is a rectangular prism that is 18 inches long, 12 inches wide and 9 inches tall. How much wrapping paper will she need? Group of answer choices

i think she would need about 78 inches of wapping paper

Step-by-step explanation:

She will need 3 more inches of wrapping paper to wrap the box.

Step-by-step explanation:

add 12 and 9 the subtract the answer by 18

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)
