Answer:
10x^2 (x+2) (x+6)
Step-by-step explanation:
assuming you meant 120 not 1120
10x^4+ 80x^3 + 120x^2
factor out 10 x^2
10x^2 (x^2 +8x+12)
what numbers multiply together to get 12 and add together to get 8
2*6 = 12 2+6 = 8
10x^2 (x+2) (x+6)
B and D are the same answer?????
Answer:
x = -4; y = -3
Step-by-step explanation:
2x - 5y = 7
3x - y = -9
Rewrite top equation. Multiply both sides of bottom equation by -5. Add equations. This eliminates y, and we solve for x.
2x - 5y = 7
(+) -15x + 5y = 45
----------------------------
-13x = 52
Divide both sides by -13.
x = -4
Substitute -4 for x in the first original equation and solve for y.
2x - 5y = 7
2(-4) - 5y = 7
-8 - 5y = 7
-5y = 15
y = -3
Answer: x = -4; y = -3
-5 =
