Answer:
C. 3h - 6
Step-by-step explanation:
Answer: x = 1.32 and x= 0.076
Step-by-step explanation:
4x(5x-2) = 20x-2
20x^2-8x = 20x-2
20x^2-8x-20x+2=0
20x^2-28x+2=0
Using quadratic equation
x = (-b +or- √(b^2-4ac))/2a
a =20, b=28, c= 2
Substitute into the equation
x= (7+√39)/10. = 1.32
x = (7-√39)/10 = 0.076
