Please give step by step explanation (2x + 3)(3x - 5)

6^{2} - 19x + 15

Step-by-step explanation:

Expand

(2x−3)(3x−5)

using the FOIL Method.

2x(3x)+2x x -5 -3 (3x) -3 x -5

Simplify and combine like terms.

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

the answer i believe is 27 units.
