Step-by-step explanation:
if that's x^2+25
they can be factored to x+5
because the factor of x^2 is x cause x multiplied by x is x^2 and the factor of 25 is 5 cause 5×5 is 25
Answer:
16
Step-by-step explanation:
6+8+10+20=44+16= 60 divided by 5 is 12
Answer: Choice A) There must be a vertical asymptote at x = c
Explanation:
The first limit 
says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.
The limit 
means that as x approaches c from the right side, the y values head off to positive infinity.
Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.
Answer:
12
Step-by-step explanation:
This can be solved by working backwards.
7 is one more than half the number of invitations.
Subtract 1. 6 is half the number of invitations.
Double.
12 is the full number of invitations.
Algebra (if you must!):
x = number of invitations
x/2 + 1 = 7
Subtract 1.
x/2 = 6
Multiply by 2.
x = 12
16n+8=4
16n=4-8
16n=-4
n=-4/16
n=-1/4.
