Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)
so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3
simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3
your answer would be the third option
Answer:
Step-by-step explanation:
what do you need help with
15% becomes 0.15
multiply it by 8700
0.15x8700=1305
<span>-6f+13=2f-11
-6f - 2f = -11 - 13
-8f = -24
f = 3</span>
