Your answer

Please check the explanation!

Step-by-step explanation:

Given the expression what Lizzet said was correct

No, she is not right. Let me solve the expression

Let us solve the expression

         ∵  

                ∵  

Therefore, the correct expression will be:

which can be further simplified such as:

1010: 3030

is it i think

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
