Answer:
2(9+6)
Step-by-step explanation:
32 divided by 8 equals 4.
Recall your d = rt, or distance = rate * time
notice, the time he took to cover 63 miles with the wind, is the same amount of time he took against it with 51 miles only, let's say, he took "t" hours long
and he was cycling at a rate of "r"
thus

solve for "r"
Well you would reverse the equation when it is solved, ie:
d = 1/2 + 3/4
and it would be the last answer, or 1.25 miles
Put (a+h) where x is and simplify to the extent you desire.
f(a+h) = (a+h)^2 +3(a+h) +5
= a^2 +2ah +h^2 +3a +3h + 5
f(a+h) = a^2 +3a +5 +h(2a +3) +h^2
