  16√2 ≈ 22.63

Step-by-step explanation:

A graph is informative. It shows us the sides of the polygon have slopes of ±1, so the perimeter can be figured in units of the diagonal of a unit square. (The length of that diagonal is √2.) The short sides are 3 such units long, and the long sides are 5 such units. Then the total perimeter is ...

  P = 2(3 +5)√2

  P = 16√2 ≈ 22.63

no he doesnt because "-16' is negatiive

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)
