Which steps will generate an expression equivalent to 20(x + 17)? a. Add x and 17 to get 17x, and then multiply that by 20.
b. Multiply 20 by x and then add 17.
c. Multiply each term in the parentheses by 20 and then add the products.
d. Add x to the product of 20 and 17.

C)

Step-by-step explanation:

50.6

step-by-step explanation:

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
