Answer:
c. the zeros, -24 and 24, can be found when 0= (x+24)(x-24).
Step-by-step explanation:
The given function is
![g(x)=x^2-576](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E2-576)
When we equate the function to zero, we obtai;
![x^2-576=0](https://tex.z-dn.net/?f=x%5E2-576%3D0)
Use difference of two squares:
![x^2-24^2=0](https://tex.z-dn.net/?f=x%5E2-24%5E2%3D0)
![(x-24)(x+24)=0](https://tex.z-dn.net/?f=%28x-24%29%28x%2B24%29%3D0)
Use the zero product property to obtain;
![x-24=0,\:and\:x+24=0](https://tex.z-dn.net/?f=x-24%3D0%2C%5C%3Aand%5C%3Ax%2B24%3D0)
This implies that;
![x=24,\:and\:x=-24](https://tex.z-dn.net/?f=x%3D24%2C%5C%3Aand%5C%3Ax%3D-24)
The correct choice is C
Answer:
see explanation
Step-by-step explanation:
Given
(x - 3) × (x + 4) = 0, that is
(x - 3)(x + 4) = 0
The zero product indicates that (x - 3) = 0 or (x + 4) = 0
x - 3 = 0 ⇒ x = 3
x + 4 = 0 ⇒ x = - 4
Thus if x = 3, then
(3 - 3)(x + 4) = 0 × (x + 4) = 0
Similarly if x = - 4 the output is zero
D = 90
This is because any line is equal to 180 degrees, we see that d is situated on a line that continues into another angle, the other angle is 90 degrees, so we minus 90 from 180, to get 90.
E = 99
E is situated on a line with the other angle F, F = 81 (see below) so we minus 81 from 180
F = 81
F is situated on a line, we minus it from the other angle situated on the same line, so we minus 99 from 180to get 81
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
Answer:
A. The car travels 65 miles in one hour
B. 97.5 miles
C. 24 Minutes
Step-by-step explanation:
The answer would be 40
-4(-2) = 8
8(5) = 40
