the grade of a road is its slope written as a percent. a very steep street has a maximum rise of 11 meters for a horizontal distance of 14.82 meters. find the grade of this section of road

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

47 - 90 = 43

43 - 180 = x

x = 137

combine all like terms then its just a 2 step equation
