11. find the value of x.
|(6x + 7)º
(8x – 17)

(6x+7)(8x−17)

Step-by-step explanation:

(6x+7)(8x+−17)

=(6x)(8x)+(6x)(−17)+(7)(8x)+(7)(−17)

=48x2−102x+56x−119

=48x2−46x−119

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

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
