Simplify this expression: the sum of three and a number is added to twenty-four

x + 27

Step-by-step explanation:

Let "a number" = x.

"The sum of three and a number" = 3 + x

"is added to twenty-four" = + 24

3 + x + 24

Simplify. Combine like terms:

x + 3 + 24

x + 27

x + 27 is your answer.

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

my guess is
