Explain why the polynomial 144x^2 − 200x + 81 is not a perfect square. a. 81x ≠ 2(20x ∙ 9) b. 144x ≠ 2(20x ∙ 12) c. 200x ≠ 2(9x ∙ 12) d. 200x ≠ 2(12x ∙ 9)

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Which expression is equivalent to -5(3x - 6/7)
