B=h+4, m=h-2 now we are told
b+h+m=11, using b and m found above in this equation gives us:
h+4+h+h-2=11
3h+2=11
3h=9
h=3 and since b=h+4, m=h-2
historical=3, biography=7, mystery=1
Nothing crazy here, just a matter of figuring out the limits of integration.



<h3>
Answer: 12</h3>
========================================================
Explanation:
You can use the AAS (angle angle side) theorem to prove that triangle ABD is congruent to triangle CBD.
From there, we can then say that AD and DC are the same length
AD = DC
3y+6 = 5y-18
3y-5y = -18-6
-2y = -24
y = (-24)/(-2)
y = 12
Answer: 3x or 300%
Explanation: Divide 54 by 18 to get 3.
