I WILL MARK U AS BRAINLIEST CAN SOMEBODY PLS HELP ME

#1      45√ 5      

#2  504

#3  X1=-15, X2=1

Step-by-step explanation:

9 √5^2 x 5

9 √5^2  √5

9 x 5 √5

45 √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)

do your own work and don"t cheat.
