Answer:
quadratic
Step-by-step explanation:
Given
x²y - 2xy - 24y ← factor out y from each term
= y(x² - 2x - 24) ← quadratic factor
To factor the quadratic
Consider the factors of the constant term ( - 24) which sum to give the coefficient of the x- term (- 2)
The factors are - 6 and + 4, since
- 6 × 4 = - 24 and - 6 + 4 = - 2, hence
x² - 2x - 24 = (x - 6)(x + 4) and
x²y - 2xy - 24y = y(x - 6)(x + 4) ← in factored form
Let the number of nickels be n, then the number of quarters is 84-n.
The value of 1 qtr is 25c and the value of 1 nickel is 5c.
The total value is 5n+25(84-n)=1240 (in cents).
5n+2100-25n=1240, 20n=860, n=860/20=43.
So there are 43 nickels (worth $2.15) and 41 quarters (worth $10.25).
Answer:
There are 11 cows that eat a random amount of wheat everyday, and there is one cow that eats 25 wheat. If you know that there are 201 wheat gone how many wheats did the 11 cows eat that day
