Area of the square 5.4ft and 4ft

29.16 and 16

Step-by-step explanation:

A square's sides are always the same as another. So the area of a square with a side as long as 5.4 would be 5.4 squared. That equals to 29.16. The 4ft sided square is 4 squared. That equals to 16.

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)
