The side lengths of a square increase at a rate of 4cm/s. Find the rate at which the area of the square is increasing when the side length is 2cm. g

4 cm^2/cm

Step-by-step explanation:

The area of a square is given by the equation:

To find the rate at which the area increases, we just need to find the derivative of the area in relation to the side:

So, when the side length is 2 cm, the rate at which the area increases is:

When the side length is 2 cm, the area increases at 4 cm^2/cm.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
