B 3.2 - 3
С None of the above

Answer 1

18x + 20

Explanation:

5 + (-3)(6x - 5)

Step 1. start by the parentheses (by multiplying (-3) by (6x - 5)

Answer: (-18x + 15)

Step 2. Add 5 to (-18x + 15)

Thus, (-18x + 20) isn't a choice so None of the above

Answer 2

`\\ \sf\longmapsto 5+(-3)(6x-5)`

`\\ \sf\longmapsto 5-3(6x-5)`

`\\ \sf\longmapsto 5-18x+15`

`\\ \sf\longmapsto -18x+15+5`

`\\ \sf \longmapsto -18x+20`

Option C is correct

None of the above
