Happy Valentines Day!

Answer:

C. 5

Step-by-step explanation:

32 / 4 = 8

Both triangles represent a translation where the triangle on the left is bigger than the one on the left which means the one on the left has to have something similar which in this case there is a side on both triangles that have a measurement which lets us start on solving the question.

Let ​ x² + 15x = 49 .​
Aleks04 [339]
Since the numerical coefficient of the first term is only 1, we determine the number that needs to be added to both sides of the equation by squaring half of the second term. That is,
                                   third term = (15/2)² = 56.25
Thus, the missing terms are,
                          x² + 15x + 56.25 = 49 + 56.25
equal to,
                            x² + 15x + 56.25 = 105.25
