Given the rectangles perimeter find the unknown side length

What you have to do: 150 + 150 = 300. 1000 - 300 = 700. So 700 either divide that by two or find the square root. It’s either way. Im not quite sure ask your teacher or say you are confused on whether to find the square root or subtract.

answer: i guess 5 units?

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)
