Answer:
41
Step-by-step explanation:
76 + 63 = 139
180 - 139 = 41
I believe the answer you are looking for it -780
times by a on both sides
a(a+8)= -5
expand brackets
a^2 + 8a = -5
minus 5 on both sides to set equal to 0
a^2 + 8a -5 = 0

Correct Answer:
Option 3. The quadratic function has two distinct real zeros.
The number of distinct real zeros of a function is equal to the number of x-intercepts of the function. In this case the quadratic function has 2 x-intercepts at 2 different places, this signifies that the function has 2 real zeros. Since the function is quadratic it can have only 2 zeros.
The knowledge of y-intercept is extra and has nothing to do with the number of zeros of the function.
