Represent the polynomial x2 – 16 geometrically using algebra tiles. The number of zero pairs that will be added to the board is
.

The equivalent factored form of x2 – 16 is
.

X+ y = k 2x + 3y = k + 1 the point of intersection of the lines has an x-coordinate of a.2k + 1 b.-2k + 1 c.2k - 1

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.
