Question

Please evaluate: 2x^2+2y for x=5, y=3

Answer 1

Well, what do you get if you plug those values in?

Answer 2

Could you explain it? I don't understand it

Answer 3

Your original equation is 2x^2 + 2y, so put your values in there. They tell you that x = 5, so it would be 2(5)^2 + 2y.

Answer 4

And then you'd also put the y value in, which would give you 2(5)^2 + 2(3) since they tell you that y = 3.

Answer 5

Then you just use arithmetic and solve that.

Answer 6

2x2+2y@x=5;y=3
2(52)+(2)(3)
= 56

Answer 7

Correct?

Answer 8

Yep! Nice job.

Answer 9

Ok, thanks a lot! :D

Answer 10
