Answer:
x3
Step-by-step explanation:
You add 5 to both sides. Then divide it by 4 to get your answer.
A is the answer probably but not too sure
Answer:
They have no minimum y -value
the point that the function intercepts the x axis are the zeros of the function, where the products set equal to zero give you the x coordinate in which it intercepts.
x=-15 and x=9
set both equal to 0
x+15 and x-9
These are your two products
(x+15)(x-9)
or
x^2+6x-135
