Can someone me solve -6x + 6(3x-4xy)

Parentheses can be eliminated using the distributive property

-6x +6(3x -4xy) = -6x +18x -24xy

Like terms (those with the variable x only) can be combined

x(-6+18) -24xy = 12x -24xy . . . . . simplified

In some cases, you may be interested in factoring the expression. 12x is a common factor for the two terms, so another way to write this expression is

... 12x(1 -2y)

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
