Tyree says that he cannot simplify 3n + 4 anymore than it is already simplified. Why is that? A
3n and 4 do not have the same coefficient.

B
3n and 4 are not like terms.

C
He is incorrect; they can be simplified.

D They do not have the same exponent.

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
