Answer:

(x - 6)(x - 6)

Step-by-step explanation:

The given quadratic equation is $ x^2 - 12x + 36 = 0 $.

A quadratic equation can be factored in the form $ (x - a)(x - b) $ where $ -a $ and $ -b $ will form the roots of the equation.

Here the roots are: $ +6 , +6 $.

The factored form would simply be:  $ (x - 6) (x - 6) $.

A company offers you a job with an annual salary of $70 000 for the first year and a 5% raise every year after. Approximately ho
mariarad [96]

Answer:

$386794

Step-by-step explanation:

To be able to find how much we get in 5 years, we need to base it off the initial salary value.

So in the first year we get.

$70,000

To get how much we get in the 2nd year we add the extra 5%.

2nd year salary = (1.05)70000

2nd year salary = 73500

Now we continue to do that until the 5th year

3rd year = (1.05)73500

3rd year = 77175

4th year = (1.05) + 77175

4th year = 81033.75

5th year = (1.05) + 81033.75

5th year = 85085.44

Now we add them all up to get the total.

70000 + 73500 + 77175 + 81033.75 + 85085.44 = $386794.19 or $386794

A girl is 18 years old and her brother is a third of her age. When the girl is 36 what would be the age of the brother?
ale4655 [162]
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old

Now when she gains another 18 years (36-18=18) he will also gain those 18 years

When she is 36 he will have 6+18=24 years old

Answer is 24.
