Answer:
20
Step-by-step explanation:
you would take 8 times 2.5 to figure that out
(-2d^2+s)(5d^2-6s)
= (-2d^2*5d^2 + s*5d^2 -2d^2*-6s + s*-6s
= -10d^4 + 5sd^2 + 12sd^2 - 6s^2
=-10d^2 + 17sd^2 - 6s^2
This is the final result
Answer:
4.10
5. 16
6. B.
7. B.
8. A.
Step-by-step explanation:
I believe this would be it. Hoped this helped!
