Use completing the square to find the value to add that makes x^2 - 12x a perfect square trinomial. Then write the expression as
yarga [219]

Answer:

Step-by-step explanation:

If you want to make

x^2-12x

into a perfect square binomial, take half the linear term, square it, then add it to both sides.  Our linear term is 12.  Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

(x^2-12x+36)-->(x-6)^2

Suppose that Bob leaves a job that pays $100,000 per year in order to open a new sponge business. His insurance cost is $8,000,
tensa zangetsu [6.8K]

Answer:

-$11,000 is the economic profit or we can say it is a loss.

Step-by-step explanation:

The job paid Bob = $100000

The insurance cost is = $8,000

The material cost is = $15,000

The lease payments are = $8,000

The sales revenue is $120,000.

So, Bob's economic profit is: 120000-100000-8000-15000-8000=-11000

Therefore, his economic profit is -$11000.

Penelope decides to reduce her math tutoring to half the amount of time she has been tutoring each month. After making this chan
Shalnov [3]

Answer: $300 per month (assumed)

Step-by-step explanation:

As figures are lacking in this question, I will use assumed figures and you can use it as a reference.

Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.

If she reduces this time to half, the amount of hours she begins to tutor is:

= 60 hours / 2

= 30 hours

At a rate of $10 an hour, her monthly income becomes:

= 10 * 30

= $300 per month
