What is the simplified form of the quantity of x plus 4, all over 5 + the quantity of x plus 5, all over 5 ? (2 points) the quantity of x squared plus 9x plus 20, all over 5
the quantity of 2x plus 9, all over 5
the quantity of x squared plus 9x plus 20, all over 25
the quantity of x plus 4, all over the quantity x plus 5

if this is really you s much. i only have 3 points left and i have 2 questions to ask

it would be:

c.parallelogram.

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
