2. A, but you need parentheses in 5+4

3. A

4. D

5. I'm having a bit of confusion. is "x" a multiplication sign or is it a variable?

Evangeline Hogan · Answer 2

1) y = 3

2) C.) 8 * 60 - 8 * 6 ⇒ it will look like this 8 (60-6) ⇒ 8 (54)

3) A) 7u + 5v

4) 4x³ and x³ are like numbers

5) Simplify: 5x³ - 2x² + x + 4x³

group like numbers: 5x³ + 4x³ - 2x² + x

9x³ - 2x² + x ⇒ letter C.
