A boy owns 5 pairs of pants, 3 shirts, 8 ties, and 7 jackets. How many outfits can he wear to school if he must wear one of each item?

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
