Answer:
-x^4 - 2x^3 +2x + 5
Step-by-step explanation:
(x + 3) – [(x + 2) (xᶺ3 – 1)]
(x + 3) - [(x^4 - x + 2x^3 - 2)]
(x + 3) - (x^4 - x + 2x^3 - 2)
-x^4 - 2x^3 +2x + 5

I think u should divide 8 and 10 then u will get your answer hope that helps
Answer:
32768
Step-by-step explanation:
Each question has 2 options.
On a true/false test with one question, there are 2¹, or 2 possible answers
On a test with 2 questions, there are 2², or 4 possible answers.
On a test with 3 questions, there are 2³, or 8 possible answers.
So, 2¹⁵ = 32768 possible ways.
