First one right gets BRAINLIEST!!

If f(x)=x²+2x-3 and g(x)=x²-9, find (f/g) 4 and (f+g)(4)

3 and 28

Step-by-step explanation:

note ( )(x ) =

=  and

( )(4) = = = = 3

-------------------------------------------------------

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= x² + 2x - 3 + x² - 9 = 2x² + 2x - 12 and

(f + g)(4) = 2(4)² + 2(4) - 12 = 2(16) + 8 - 12 = 32 + 8 - 12 = 28

the answer is 62.8 cubic units
