Answer: -4n3+12n2+7n-9
Step-by-step explanation: it basically the opposite sign (positive or negative) switched, and the order backwards. hope that helped
Answer:
x=(y+9)/(1+2w)
Step-by-step explanation:
x-9+2wx=y
We make x the subject
x+2wx=y+9
x(1+2w)=y+9
Divide both sides by (1+2w)
x(1+2w)/(1+2w)=y+9(1+2w)
x=(y+9)/(1+2w)
First, you do the distributive property on:
4(2n+3)
You would get
8n+12
Then add the original part of the equation in (4n)
4n+8n+12
Combine like terms
12n+12 is the answer
I'm not 100% positive but I believe it would be the 14th person. 10+4=14. That's just my guess.
