Which expression is equal to/¿Qué expresión es igual a/ Quelle expression est égale à
8 4
9 x 5

answer: ouch. thats difficult

step-by-step explanation:

x=30

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

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
