(3p-10q)-(p-8q)
I can’t figure this out !!!

2p - 2q

Step-by-step explanation:

(3p-10q)-(p-8q) is simply an algebraic expression.

To solve it, you first open the brackets

i.e 3p - 10q - p + 8q (the minus sign between the brackets have multiplied the next minus sign, so it becomes plus sign)

Now, collect the like terms of i.e common terms

= 3p - 10q - p + 8q

= 3p - p - 10q + 8q

= 2p - 2q

Thus, the final expression is 2p - 2q since it cannot be further simplified.

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
