Answer:
C. x^2 -4
Step-by-step explanation:
What you do is subtract the functions as said by
(f-g)(x).
so:
f(x)-g(x)
(2x^2+3) - (x^2 -7)
2x^2 -x^2 +3 - 7= x^2 -4
Answer:
166.666667 m/ps
Step-by-step explanation:
600/60 will give us the amount of kilometers in a minute. 10 km/ph, now i'll divide more to find the seconds. 0.166666667 this is the amount of KILOMETERS in a second, we are trying to find in meters. multiply by 1000 and 166.666667. a fast fricking train if you ask me.
Answer:
28
Step-by-step explanation:
AB + BC = AC
14 + 3x-4 = 4x+4
Combine like terms
10 +3x = 4x+4
Subtract 3x from each side
10+3x-3x = 4x+4-3x
10 = x+4
Subtract 4 from each side
10-4 =x-4+4
6 =x
We want AC
AC = 4x+4 = 4*6+4 = 24+4 = 28
