7w + 5y - 2w + 4 + 5y - 10 - w

Answer 1

To simplify the expression, we can combine like terms:

7w + 5y - 2w + 4 + 5y - 10 - w

= (7w - 2w - w) + (5y + 5y) + (4 - 10)

= 4w + 10y - 6

Therefore, the simplified expression is 4w + 10y - 6.

Answer 2

-10(2x - 8)

Answer 3

To simplify the expression, we can distribute the -10 to every term inside the parentheses:

-10(2x - 8) = -10 * 2x - 10 * -8

= -20x + 80

Therefore, the simplified expression is -20x + 80.
