i was wondering if anyone could help me on this problem. expand: x^2 (y^2 + 10x) z^3 (5x + 3z^4) First one: x^2 (y^2 + 10x) x^2 is the same thing as 1/x^2. Therefore, we have this: 1/x^2 (y^2 + 10x) Multiply using the

Thanks Reiny, but I'm still lost. I understand how you multipled by 10X on the right to get 17x, but you went too fast on the left, and I have no idea how you got 10x^220 from the starting left side. Can you show each step?

Find the equation of the tangent line 5x^2+y^2=14 at (1,3). P.S: It's calculus. So far I know this much 10x+2y(dy/dx)=o 10x 10x ___________________ 2y(dy/dx)= 10x (dy/dx)= 10x/2y= 5x/y m= 5(1)/3= 5/3 y=mx+b 3= 5/3(1)+b

Determine whether the point (1, 8) is a solution of the system 2x + 6y = 50 10x + 0y = 10 by substituting the point into each equation. So far I have: 2x=6y=50 y=502x 10x+10y=10 10x+0(502x)=10 10x+0=10 x=10 y=502x y=502(1)
