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.

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
