Will mark brainliest if right! x² + 16x = 49 . what values make an equivalent number sentence after completing the square?

64

Step-by-step explanation:

To complete the square

add (half the coefficient of the x- term )² to both sides

x² + 16x + (8)² = 49 + (8)²

x² + 16x + 64 = 49 + 64 ← equivalent expression

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
