Answer:
=2
Step-by-step explanation:
We have to make the fractions equal so we can add them
1 
×4= 1
×3=
1+=2
One method is to round 997 up to 1000, multiply by 8, and then subtract 8 times 3. This would give you the solution of 7976.
Another method (Which I personally wouldn't use) is to recursively double 997. This is more difficult, although effective. After you double 997, double the resulting number, and then double the resulting number from that, you have the solution. This is because 2^3 is 8.
Answer:
g (f(2)) = 3
Step-by-step explanation:
f (x) = x2 – 4
g(x) = x + 3
g (f (2)) =?
Find f(2) first
f (x) = x2 – 4
f (2) = 2^2- 4
= 0
Now put this in your g(x)
g(x) = x + 3
g (f(2)) = (f(2)) + 3
And u alredy know f(2) =0, so just put it in
g (f(2)) = 0 + 3
=3
