Answer:

2. Both

3. e = 3, f = -5, g = 2

Step-by-step explanation:

2. Order doesn't affect product

3. You get e • f = -15, e • g = 6, f • g = -10 from the problem.

   e = -15/f    (solve for e)

   (-15/f) • g = 6    (plug into second equation)

   (-15g/f) = 6    (multiply)

   -15g = 6f    (multiply)

   (-5g/2) = f    (divide)

   (-5g/2) • g = -10    (plug into last equation)

   (-5g^2)/2 = -10    (multiply)

   -5g^2 = -20    (mulitply)

   g^2 = 4    (divide)

   g = 2    (square root)

   e • g = 6    (plug in for g, solve for e)

   e • 2 = 6

   e = 3

   f • g = -10    (plug in for g, solve for f)

   f • 2 = -10

   f = -5

I don't know if your teacher made a typo because I tried this multiple times and got the same answer. I don't know how e is negative.

Answer:

1. both are correct

2.f=5 g=-2 e=-3

Step-by-step explanation:

for number two, because e is negative you can logically figure out that f is positive and g is negative because a negative times a negative is a positive and a negative times a positive is a negative. you are then left with

-e times f=

-e times -g=

f times -g=

then by the process of substitution and trial and error, you can logically conclude that f=5 g=-2 e=-3
