Answer:

17x² - 5x + 11 = 0

Step-by-step explanation:

To add or subtract a polynomial do the operation with like - terms.

i.e., Two terms of x² gets added or subtracted. Similarly terms of x and constant.

Here, we have to subtract:

$2x^2 + 9x - 3 - 7x^2 + 4x - 8 - 9x^2 - 13x + 5 - 9x^2 + 13x - 5 + 5x^2 - 13x - 1 + 5x^2 + 5x - 5$

Club all the like terms for easier simplification. We get:

$(-2 - 7 - 9 - 9 + 5 + 5)x^2 + (9 + 4 - 13 + 13 - 13 + 5)x + (-3 - 2 + 5 - 5 - 1)$

$\implies - 17 x^2 + 5x - 11 = 0$

Multiplying by -1 throughout:

17x² - 5x + 11 = 0 is the answer.

John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.00. After usin

professor190 [17]

The total amount they spent is the cost of pizza and 4 large drinks. This amount is also the sum of the amount of gift certificate and the cash $13.20. Let x be the price of each drink. The equation would be,
13 + 4x = 6 + 13.20
The value of x from the equation is 1.55. Thus, each large drink costs $1.55.
