Answer:

  (y +1)

Step-by-step explanation:

When you multiply the binomials (ay+b)(cy+d), the product is ...

  acy² +(ad +bc)y +bd

In this problem, you know the product and you know one of the factors (ay+b) = (5y -7), so ...

  • ac = 5
  • a = 5
  • bd = -7
  • b = -7

These tell you ...

  c = ac/a = 5/5 = 1

  d = bd/b = -7/7 = 1

Then the other factor is ...

  (cy+d) = (y+1)

____

<em>Check</em>

We can check this by looking at the y-term:

  (ad+bc) = -2 . . . . from the given polynomial

  (5)(1) +(-7)(1) = 5-7 = -2 . . . . answer checks OK

Answer:

the answer would be 90

Step-by-step explanation:

100 giants fills 5/8 (100/160) of the theater leaving 3/8 of the theater for the elves.

3/8 times 240 elves is 90 elves.

If there were 150 elves that would also be 5/8 filled plus the original 5/8 filled with 100 giants! Some elves might suffer!!!
