To show that polygon abcde is congruent to polygon fghij, a must be used to make the two polygons coincide. a sequence of two transformations that can be used to show that polygon abcde is congruent to polygon fghij is .

What is the expression in factored form? 225x^2 - 144 a. 9(5x+4)^2 b. 9(5x-4)^2 c. 9(4x+5)(4x-5) d. 9(5x+4)(5x-4)

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
