Answer 1

∫[1,2,1/[(x+2)^2√((x+2)^2+16)],]=dx/u√(u^2+16)=[√(u^2+a^2)]/(a^2u) for u=x+2 and a=16

Answer 2

\[y=3\chi ^{2}+\chi+1\]

Answer 3

? how do you graph that?

Answer 4

how do i solve this system:
5x+2y =7
-x/2 + y/6 = 3/2

Answer 5

i used to know but I forgot sorry

Answer 6

2+2=

Answer 7

FISH!!!!!!

Answer 8

In ∫ 2x(x^(2)+3)dx, if we let u=x^(2)+3,then
1.the integral form is u^(n)du and du=2x
2.the integral form u^(n)du cannot be used because n=1
3.the integral form is u^(n)du and du=2dx
4.the integral form is u^(n)du and du=2xd
