Answer:

The answer is $(x^3-8)(x^3+2)$

Step-by-step explanation:

Find two factors that equal -6 when added, and -16 when multiplied. Those are your outer numbers. The exponent of the first term is a 6, so you know when you multiply two numbers with exponents, you add them. 6/2=3.

I'm really sorry for the bad explanation, I was in a hurry. Sorry. But I know the answer is correct.

Toms sounds at 9, 18, 27, 36 minutes after it initially sounds

Amy’s sounds at 12, 24, 36 minutes

so at 721am 36 minutes after they went off both Tom and Amy when they woken up,they were both late.
