Answer:
68.4 miles
Step-by-step explanation:
7.6 * 9 = 68.4
F(x) = f(-x) is even, and f(-x)=-f(x) is odd. to know if it's even or odd you take the function and plug in -x for x then simplify it. if it's the same function that you started with , it's even. for example
if you have this
f(x) = -3x^2+4
plug in -x for x which will turn out to be
f(-x) = -3(-x)^2+4
and when simplified it'll be
-3x^2+4 because (-x)^2 is (-x)(-x) which is a positive.
because it's the same, it's an even one.
Answer:
-4
Step-by-step explanation:
2-26=-24
-24-(-20) basically says -24+20=-4
Answer:
(3n + 4) (n-2)
Step-by-step explanation:
Are you asking to factor this 3n^2 - 2n -8 ?
If so the best way to do this problem is with the X method.
top: 3*(-8)
left: factor of 3*-8 right: factor of 3*-8
bottom: -2
try the factors 4 and -6 because 4*-6 = 3 *-8 = -24
Because notice that 4 + -6 = -2
so:
3n^2 -2n - 8 can be rewritten as 3n^2 -6n + 4n - 8
We should first use Distributive property to factor: 3n^2 -6n + 4n - 8
3n^2 -6n + 4n - 8 = 3n (n - 2) + 4(n - 2)
Now we factor by grouping here : (3n + 4) (n-2)
I factored out the group (n-2)
Therefore: (3n + 4) (n-2) = 3n^2 -2n - 8
