Answer:
Step-by-step explanation:
(10x + 8)^0 = 1
(9x+18) if x = 8 = 9*8 = 72 + 18 = 90
12x - 10
12 * 8 = 96 - 10 = 86
(1) ( 90) ( 86)
if you need to multiply them them do so

Answer:
4 (5/12). four and five-twelfths
Step-by-step explanation:
1/2 is the same as 2/4, so: 1 1/2 = 1 2/4
1 2/4 + 2 1/4 = 3 3/4
3/4 and 2/3 have a LCM or least common multiple of 12
4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)
9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number
3 + 1 5/12 = 4 5/12
