c. 64
d. 54

Answer 1

take the derivative, replace x by 1

Answer 2

my answer is 64 i got wrong... i just wanted to know the answer...

Answer 3

\[x^2(x+2)^2=x^2(x^2+4x+4)=x^4+4x^3+4x\]
\[y'=4x^3+12x^2+4\]
i get 20

Answer 4

the answer is in the letter i just forgot..and i need it

Answer 5

oh i made a mistak

Answer 6

\[x^2(x+2)^2=x^2(x^2+4x+4)=x^4+4x^3+4x^2\]
\[y'=4x^3+12x+8\] now i get 24
