If y = x3 + 2x and dx, dt equals 5, find dy, dt when x = 2. Give only the numerical answer. For example, if dy, dt = 3, type only 3.

dy = 10

Because y is 10 and i assume d is 1 because dt = 5

70

Step-by-step explanation:

The answer is not 10, as the person above said.

First do the derivative of x^3 + 2x:

3x^2 + 2

Then plug 2 in for x and multiply each term by 3

(3 (2) ^2 * 5) + (2*5) = 70
