(the difference of d minus 3 divided by 2)

(d-3)/2

Step-by-step explanation:

Given:

A number "d" Subtract by 3

So,

⇒ (d-3)

Product is divided by 2

So,

⇒ (d-3)/2

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. side angle side. u shares the same sides
