f(x)=2x^{2}+8 \\  \\ g(x)=5x-6 \\  \\ (f+g)(x)=2x^{2}+8+5x-6=2x^{2}+5x+2 \\  \\ (f*g)(x)=(2x^{2}+8)(5x-6)=10x^{3}-12x^{2}+40x-48

Which shows a correct order to solve this story problem? Each morning Mike bikes 3.5 miles. Each afternoon he bikes 2.3 miles. H
Grace [21]
Ok so
since we h ave
3.5=1 day's morning
and
2.3=1 day's afternoon
we need to add them to find 1 day and multiply by 6 (number of days)
that answer is not listted so we make into anohter form
this wold be
6 times (3.5 +2.3)
if we distributed
a(b+c)=ab+ac
6(3.5+2.3)=6 times 3.5+6 times 2.3

this is D
