Answer:
2, 4, 37
Step-by-step explanation:
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
12 - 25 is equal to -13.
Just think of it as 25 minus 12. This gives you 13. Then put a negative sign in front of it.
( 25-10 / 17 - 3.4 ) - 1
( 15 / 13.6 ) - 1
1.4 - 1
Change one "x" to a positive by multiplying everything to a -1. Then add the equations to make one, solve for "y". After you get "y" plug it in to get "x". Hope that helps.
