Let
f(x) = x^2 + 5x
and
g(x) = 2x^2 − 4.

Find the function.
f + g

(f + g)(x) = ?

f + g  = 3x^2  + 5x - 4

Step-by-step explanation:

We see addition of functions.

f(x)  = x^2  + 5x

g(x) = 2x^2  - 4

Simply add the expressions.

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

f + g  = 3x^2  + 5x - 4

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
