What is the result when 4x3 + 18x2 +22x + 5 is divided by 2x + 5?

10.6 + 11x

Step-by-step explanation:

4×3 + 18×2 + 22x + 5 / 2x+5

12 + 36 + 5 + 22x / 2x + 5

53 + 22x / 2x + 5

10.6 + 11x

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
