Too Confusing !!
but I think it's
g(x)=(x^2+4x-12)(x-3)
=(x+6)(x-2)(x-3)
=x+6 = 0
-6 -6
x=-6
x-2 = 0
+2 +2
x=2
x-3 = 0
+3 +3
x=3
The zeros are {-6, 2, 3}
hope this helps ! :)

#4 through #8: same thing
9.) Chan Hee bought 3.4 pounds of coffee. He spent $6.95 per pound.
To solve this problem, you need to multiply 3.4 by $6.95, to find out how much money that Chan Hee spent on the coffee, in total.
3.4 (6.95)
Now try #10 on your own.
Remember that you want to find out the total amount of money Adita earns by multiplying.
11.) By looking at the chart, you can find out what values you have to multiply.
Focus on Week Two.
Multiply the cost per gallon with gallons bought.
12.) Do the same thing as #11, but for Weeks 4 and 1 separately.
Now, subtract the final value from Week 1 fron Week 4. Remeber to line up the decimals.
Good luck and if you need more help, please message me.

I don't know any slick way to do this. I would just list the prime numbers
between 40 and 50 and test them one at a time.
The prime numbers between 40 and 50 are: 41, 43, 47
Test 41:
-- add 1 . . . 42
-- prime factors of 42 . . . 2, 3, 7
-- sum of the factors . . . 12
Test 43:
-- add 1 . . . 44
-- prime factors of 44 . . . 2, 11
-- sum of the factors . . . 13
Test 47:
-- add 1 . . . 48
-- prime factors of 48 . . . 2, 3,
-- sum of the factors . . . 5
Maybe I'm not understanding how to list prime factors, but so far,
I haven't found any number that answers the question.
Maybe if I write the prime factorization of 44 like this:
44 = 2 * 2 * 11
Now the items in the prime factorization do add up to 15.
So the answer would seem to be 43.
