The expression x2y - 2xy - 24y can be factored by first factoring out a common factor of y.

gladu [14]

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

Answer:

The direct distance between the birds is 12.64 miles.

Step-by-step explanation:

We have, one bird flew 12 miles west and another bird flew 4 miles north. It is required to find the direct distance between the birds. It means we need to find the resultant of two displacement. It can be given by :

$d=\sqrt{12^2+4^2} \\\\d=12.64\ \text{miles}$

So, the direct distance between the birds is 12.64 miles.
