Answer:

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

F(x) = 3x^2 + 4x - 7 g(x) = 5x - 3 Find (f +g) (x)

snow_tiger [21]

$f(x) = 3x^2 + 4x - 7$ $g(x) = 5x - 3$

$(f + g)(x) = f(x) + g(x)\\= (3x^2 + 4x - 7) + (5x - 3)\\= 3x^2 + 4x - 7 + 5x - 3\\= 3x^2 + 9x - 10$
