Let x² + 15x = 49 . what values make an equivalent number sentence after completing the square? enter your answers in the boxes. x^2+15x+ =

for completing the squares , we have to add both sides the square of half of coefficient of x

So we add both sides

or

So these values will make it equivalent for completing the squares

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
