M'NO'P has vertices at M(3,4),N6,4, 0 (6, 7), and P(3,7). The
center of dilation is the origin. MNOP has
vertices at M(4.5, 6), N(9,6), O (9, 10.5),
and P (4.5, 10.5). What is the algebraic
representation of this dilation?

  Dilation(origin, 2/3)

Step-by-step explanation:

The coordinate values of the image are 3/4.5 = 2/3 times those of the pre-image.

Different authors write these dilations different ways. Essentially, it is ...

  transformation(center, scale factor) = Dilation(origin, 2/3)

Your required format likely will vary.

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c
