Answer:
9x^2+4x+5
Step-by-step explanation:
f ( x ) = 5x^2 - 2x + 6
g ( x ) = 4x^2 + 6x - 1,
Add the functions together
f(x)+ g(x) = 5x^2 - 2x + 6 + 4x^2 + 6x - 1
Combine like terms
=9x^2+4x+5
There's 40 dogs and each gets 5 minutes. 40 times 5 is 200. The morning so will be 200 minutes or 3 hours and 20 minutes
The correct answer would be 6.
To figure this out, you take the square root of 36 since area of a square is side x side.
