Answer:
x = 1
Step-by-step explanation:
-5x-(-7-4x)-2(3x-4)
-5x + 7 - 4x - 6x + 8 First step is to factor all the numbers out so you have no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.
-15x + 15 In this step you combine like terms.
-15x = -15 Next you move the whole number to the other side of the equation by subtracting it from both sides.
x = 1 Finally you divide -15 by -15 to get x by its self.
It is given in the question that
A rectangular box has a square base with an edge length of x cm and a height of h cm. The volume of the box is given by
And the edge length of the base is 12 cm, the edge length of the base is decreasing at a rate of 2 cm/min, the height of the box is 6 cm, and the height is increasing at a rate of 1 cm/min.
Here we differentiate V with respect to t, and we use product rule, that is
Substituting the given values , we will get

So at that moment, the volume is decreasing at the rate of
