Find the perimeter of the shape. assume all intersections are right angles. a) 8.5 b) 10 + 3 √2 c) 13 d) 13 + 2 √3 e) 15

A). 8.5

Step-by-step explanation:

just count how many squares there are and then how many half rectangles there

since there are 7 squares and 3 half

2 halfs make one whole

so add that making 8 squares and the other half makes 0.5

once u add that you get 8.5

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)
