D. 7

Step-by-step explanation:

LM = 13,

LN = 20,

Since points L, M, and N are collinear, therefore:

(segment addition postulate)

(substitution)

Subtract 13 from each side of the equation

Possible value of MN is 7.

The answer is D. 7.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
