Answer:
x^2+2x -6
Step-by-step explanation:
f(x)=2x+1
g(x)=x^2-7
(f+g)(x)= 2x+1+x^2-7
Combine like terms
= x^2+2x -6
C=pi×r2 if there is only the diameter then take half of it
The answer to this question would be 180,693 as if you add each digit in this answer then you get 27 which is divisible by 9
I think the answer is 25.5. Although, I don't know how you would have half a bike unless there was a 3 wheel bike which would make the answer 24.
The answer is D.) Neither ordered pair is a solution.
The reason being:
If we look at the ordered pair (3,-8) and plug it into the equation like so:
3(3)-(-8)4=11
9-32=11
-23=11
FALSE
Now let's look at the ordered pair (4,4):
3(4)-4(4)=11
12-16=11
-4=11
FALSE
We see that neither ordered pair works, so the answer is D.) neither is a solution.
Hope this helped :)
