Rigid motion is the way of moving an object such that after the motion the relative distance between the points stay the same in the same way that the relative position is the same. The answer to this question is dilating the figure by a scale factor of one half.
This took me a while but I'm pretty sure the answer is

I had to review perpendicular bisectors but yeah it has to do with the midpoint and point slope formula
Answer:
see below
Step-by-step explanation:
Use the distributive property:
(y^2 +3y +7)(8y^2 +y +1)
= y^2(8y^2 +y +1) +3y(8y^2 +y +1) +7(8y^2 +y +1)
= 8y^4 +y^3 +y^2 + 24y^3 +3y^2 +3y + 56y^2 +7y +7
= 8y^4 +y^3(1 +24) +y^2(1 +3 +56) +y(3 +7) +7
= 8y^4 +25y^3 +60y^2 +10y +7 . . . . . matches the last choice
The answer should be approximately 58.3%.
