Answer:

(x - 5) and (x + 1)

Step-by-step explanation:

x² - 4x - 5

consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

the factors are - 5 and + 1 , since

- 5 × + 1 = - 5 and - 5 + 1 = - 4 , then

x² - 4x - 5 = (x - 5)(x + 1)

MAVERICK [17]

Answer:

The total earnings of Carey in t tours is 12 t - 2 .

Step-by-step explanation:

For each hour he babysits, Anderson earns $1 more than half of Carey's hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey's hourly rate, c? 18 + ?T = 24 What number should be the coefficient of t?

Anderson earns $1 more than half of Carey's hourly rate.

Anderson hourly rate = $ 6

Let Carey's hourly rate is p. Let the time is t hours.

So, Anderson rate is

$6 t = \frac{p t}{2} +1\\\\2\times 6 t = p t + 2 \\\\p t = 12 t - 2$
