Question

Subtract (5x+11) from the sum of (3x^2+9x+8) and (6x^2+3x-8)

Answer 1

The total revenues in dollars for a company to sell x blank audio cassette tapes per week is given by the poly nominal function R(x)=8x. Find the total revenue from selling 40,000 types per week

Answer 2

First, we need to find the sum of (3x^2+9x+8) and (6x^2+3x-8):

(3x^2+9x+8) + (6x^2+3x-8)
= 9x^2 + 12x
= 3x(3x+4)

Now, we can subtract (5x+11) from this sum:

3x(3x+4) - (5x+11)
= 9x^2 + 12x - 5x - 11
= 9x^2 + 7x - 11

Our final answer is 9x^2 + 7x - 11.

Answer 3

We can use the given polynomial function, R(x) = 8x, to find the total revenue from selling 40,000 blank audio cassette tapes per week.

To do so, we substitute x = 40,000 into the function:

R(40,000) = 8(40,000)

R(40,000) = 320,000

Therefore, the total revenue from selling 40,000 blank audio cassette tapes per week is $320,000.
