What is the factored for of the polynomial x^2 - 12x + 27
vodomira [7]

Answer:

(x - 3)(x - 9)

Step-by-step explanation:

Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (- 12)

The factors are - 3 and - 9, hence

x² - 12x + 27 = (x - 3)(x - 9 )

Jack has $6.00 less than twice the amount of money David has. Together they have $45.00. How much money does Jack have
Shalnov [3]

Answer:

Jack - $28

David - $17

Step-by-step explanation:

Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.

2d-6+d=45

3d-6=45

3d=51

d=$17

We can then substitute back and find 2(17)-6=34-6=$28.
