Question one, how do you solve this? "A, B, and C are collinear. Find AC if AB = 12 and BC = 8" Question two, can anyone solve these two problems i attached? They use Segment Addition and Angle Addition Postulates.

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)

Landon wrote that 3−2.6=4. which statement about his answer is true?

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
