Answer: The correct answer is Choice C.
For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2
This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.

15 hours will get 14×15 = 210loaves
mmcht. can't really see the graph
The third one because eighteen does not have factor that can be added or subtracted to make 3 ;)
