1)Use distributive property and then combine like terms:
12h+18+5h+6h+21=
23h+39
2)Same step as #1:
9x-1+3x+2
12x+1
I hope this helps!

Simplify:
1.) 6(2h + 3) + 5h + 3(2h + 7)
Distribute the 6 to 2h and 3 ( 6(2h) + 6(3)) as in the next step
6(2h) + 6(3) + 5h + 3(2h) + 3(7)
Multiply
12h + 18 + 5h + 6h + 21
Combine Like Terms (Remember ax = bx , ax does not equal bx^2)
(12h + 5h + 6h) + (18 + 21)
23h + 39
And since you cant combine those two terms (23h and 39) , that answer is in simplest form
Do the same thing for the next problem:
1/4(36x - 4) + 1/3(9x + 6)
1/4(36x) - 1/4(4) + 1/3(9x) + 1/3(6)
9x - 1 + 3x + 2
12x - 1 + 2
12x + 1

First thing we need to do in both of these is use the distributive property.
1. 6(2h + 3) + 5h + 3(2h + 7) = 12h + 18 + 5h + 6h + 42
now we need to combine like terms... we put all h's
together and everything else together as well.
= 29h + 58
2. 1/4(36x - 4) + 1/3(9x + 6) = 9x - 1 + 3x + 2 = 12x + 1

Remember the distributive property. a(b + c) = ab + ac
Remember to combine like terms. ax + bx + c = (a + b)x + c
Using those two, you can solve for both (I'll use brackets to more easily see things):
[6(2h + 3)] + 5h + [3(2h + 7)] =
[12h + 18] + 5h + [6h + 21] =
12h + 5h + 6h + 18 + 21 =
23h + 39
[1/4 (36x - 4)] + [1/3 (9x + 6)] =
[9x - 1] + [3x + 2] =
9x + 3x -1 + 2 =
12x + 1

1. 6(2h + 3) + 5h + 3(2h + 7)=12h+18+5h+6h+21=23h+39.
Simplify..Help!!?
Simplify:
1. 6(2h + 3) + 5h + 3(2h + 7)
2. 1/4 (36x-4) + 1/3 (9x + 6)= 9x-1+3x+2= 12x+1.

1)12h+18+5h+6h+21
= 23h + 39
2) 9x - 1 +3x + 2
= 12x +1

distribute
=12h + 6 + 5h +6h + 21
gather
=(12+5+6)h+(6+21) <--- Rev Kev pointed out I had written 2!
= 23h+27
distribute
= 9x - 1 + 3x+2
gather
=12x+1

multiply the factors first then add
12h+18+5h+6h+21=?
9x-1+3x+2=?
get the idea?
