Multiply 9 by 2a and 2, and you get 18a + 18. Another equivalent expression would be 18(a+1), which you can get by factoring the above answer.
3x + 2y - 4z/x for x=5, y=-2, z=10
3x + 2y - 4z/x
3(5) + 2(-2) - 4(10)/(5)
15 - 4 - 40/5
15 - 4 - 8
11 - 8
3
The answer is really simple. 3 quarts is more. There are 4 pints in a quart. There are 4 quarts in a gallon.
857 x 132= 113,124
