A9-foot board is cut into two pieces. if one piece is x feet long, express the other length in terms of x.

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

If you answer 2+2 you will get over 80 points
