The dimensions of a box are x units, 2 + 1 units, and 2.c units. Write an expression that represents the volume of the box, in cubic units.
Simplify the expression completely.
Write an expression that represents the total surface area of the box, in square units.
Simplify the expression completely.

step-by-step explanation:

ask goog great chance of finding the solution there

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
