Look back at your grades on the individual lessons in this unit. You may want to consider asking me to reset an assignment or quiz to higher your score, or as a means of reviewing. You should also review the lesson you scored the lowest on BEFORE taking the Unit Test. Email me (or in the text box for this assignment) let me know if you have any questions, or if you would like for me to work specific problems out for you and explain the steps in solving them. In the text box, please use 10 words or more to tell me what sections you did well on or which ones gave you the most trouble.

step-by-step explanation:

the word superfluous means unnecessary

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
