Asquare measuring x cm in side length has a cm added to its length and b cm added to its width. the resulting rectangle has an area of (x^2 + 6x + 3)cm^2. find the values of a and b, correct to 2 decimal places.

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
