Choose 1 (Choice A) A Holden used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Holden only established some of the necessary conditions for a congruence criterion. (Choice C, Checked) C Holden established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Holden used a criterion that does not guarantee congruence.

Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)

X+ y = 5 ; x - y =3 solve using linear combination
