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.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
