Can someone please help me? I'll gladly mark the best answer brainliest, and give 100 points!! Please and thank you :D

Part A: The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is 1/3. This is because triangle P'Q'R is smaller than PQR by 1/3 

Part B: The coordinates after P"Q"R" are P"(1, -2) Q"(0, -3) R"(-1, 0)

Part C: No the triangles are not congruent because they are not the same size. If there wouldn't have been a dilation or reflection then it would've been congruent. 

Step-by-step explanation:

I did this Exam already and got a 100% good luck.

First The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is 1/3. This is because triangle P'Q'R is smaller than PQR by 1/3

Second The coordinates after P"Q"R" are P"(1, -2) Q"(0, -3) R"(-1, 0)

Third  No the triangles are not congruent because they are not the same size. If there wouldn't have been a dilation or reflection then it would've been congruent. I got it right on Edge have a great day

Step-by-step explanation:

sure i'm up for it

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
