Find the slope (grade) of the treadmill if the rise is 0.7ft and the length is 2ft

0.7/2 but i think you should write it as 7/20

Step-by-step explanation:

x = -9, 1

Step-by-step explanation:

(X+4)^2-25=0

Add 25 to each side

(X+4)^2-25+25=0+25

(X+4)^2=25

Take the square root of each side

sqrt((X+4)^2)=±sqrt(25)

x+4 = ±5

Separate into 2 equations

x+4 =5            x+4 =-5

Subtract 4 from each side

x+4-4=5-4               x+4-4 =-5-4

x=1                             x=-9
