4(2x + 10)=0
8x + 40 = 0
8x = -40
x = -5
This is an easy solution heres the answer 14-24= -10
Remember you can do 24 - 14= 10 but add a negative to the answer
Answer:
The answer is: 12x
Step-by-step explanation:
I did the equation, and i got it right.
This is a parabola which looks like an inverted U. Its will have a maximum value when t = 7 as we see from the vertex form below:-
- t^2 + 14t - 40
= - ( t - 7)^2 + 49 - 40
= -(t - 7)^2 + 9
There is an axis of symmetry at x = 7.
so a is true since 7 is the maximum value of the function and its less at t = 6.
c is also true because of the symmetry about t = 7
