Since 4 balls of wool makes 8 knitted caps we'll find out how much caps each ball makes.
8/4 = 2
Each ball makes 2 caps.
6/2 = 3
Malcolm will need 3 balls of wool to make 6 knitted caps.
Answer:
The correct one is the one on the left.
(the arrow pointing to the left)
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
