Six students are working to simplify the expression shown. Drag each student's answer to a
box to show whether it is fully simplified, equivalent to
the given expression but not fully simplified, or not equivalent to the given expression.

no, because the sides are not congruent

step-by-step explanation:

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
