Solve the quadratic equation given below.

(12x – 27)^2 = 256

x

⟹

(

64

⟹

48

x

=

256

All this is straight forward. This method now requires you to add the square of the original coefficient of x to both sides of the equation.

The original coefficient is 12 so its square is 144.

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
