Subtract (5x+11) from the sum of (3x^2+9x+8) and (6x^2+3x-8)
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.
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
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.
To subtract (5x+11) from the sum of (3x^2+9x+8) and (6x^2+3x-8), we first need to find the sum of the two expressions and then subtract (5x+11) from that sum.
Let's calculate the sum of (3x^2+9x+8) and (6x^2+3x-8) first:
(3x^2 + 9x + 8) + (6x^2 + 3x - 8)
Combine like terms:
9x^2 + 12x
Now, subtract (5x+11) from the sum:
(9x^2 + 12x) - (5x + 11)
Distribute the negative sign:
9x^2 + 12x - 5x - 11
Combine like terms:
9x^2 + 7x - 11
Therefore, subtracting (5x+11) from the sum of (3x^2+9x+8) and (6x^2+3x-8) results in 9x^2 + 7x - 11.
