Which statement describes the first step to solve the equation by completing the square?

4x^2 + 16x = 20

multiply both sides of the equation by 1/4

add 64 to each side of the equation

add 8 to each side of the equation

multiply both sides of the equation by 1/8

see explanation

Step-by-step explanation:

Given

4x² + 16x = 20

To complete the square we require the coefficient of the x² term to be 1

Divide all terms on both sides by 4 or by the listed statements

multiply both sides of the equation by to obtain

x² + 4x = 5

The process of completing the square can now be performed.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
