Answer:
78x
Step-by-step explanation:
8(3x+5)+14
8 x 8x+14
64x+14= 78x
Answer:
1. $18.74x + $20 + $30
Estimated: 3x + 20 + 30 I THINK not completely sure on this estimated one.
2. is X x 2 - 9
3. is -1x + 15, step by step: group like terms: (6x - 7x) + (9 + 6) which would be -1x + 15
4. is (8n - 5.5) x 2 = 16n - 11
(5.5n + 10) x 2 = 11 + 20
group like terms: (-11 + 11 + 20) (16n) = 20 + 16n I think
5. is 1/7n + 31, second bar is 5/7n - 22, third bar is 1/7n + 26
