<span>To solve this problem, all of the data needs to be put on one side of the equation, and the sides needs to be subtracted from the perimeter. Therefore the beginning equation would be P - sides known = side unknown. (9x + 2) - ((2x -1) + (x +5) = side 3. (9x + 2) - (3x + 4) = side 3. 9x + 2 - 3x - 4 = side 3. So side 3 is (6x -2).</span>

IF ONE IS NEGATIVE AND THE OTHER IS POSITIVE WHEN MULTIPLYING IT WILL BE NEGATIVE.

WHEN MULTIPLYING TWO POSITIVE NUMBERS IT WILL ALWAYS BE POSITIVE

SAME THING IF YOU MULTIPLY A POSITIVE NUMBER WITH A NEGATIVE NUMBER YOU GET A NEGATIVE AS YOUR ANSWER

YOU NEED ONE SIGN OF THE SAME WHEN MULTIPLYING TO BE A POSITIVE AS YOUR ANSWER

YOU NEED ONE SIGN TO BE DIFFERENT FROM THE OTHER WHEN MULTIPLYING TO GET A NEGATIVE AS YOUR ANSWER
