Divide the two polynomials using long division. Then fill in the blanks below.
Ann [662]

The division of the polynomial 9x² - 6x - 8 by the polynomial 3x + 2 gives a quotient of 3x - 4 with no remainder

<h3>How to carry out the long division?</h3>

The given parameters are:

  • Dividend = 9x² - 6x - 8
  • Divisor = 3x + 2

To carry out the division, we continue dividing the leading term of the dividend by the leading term of the divisor

At the end of each division step, the quotient is multiplied by the divisor and the result of the product is subtracted from the dividend.

Using the above step, the result of the division is:

Quotient = 3x - 4

Remainder = 0

See attachment for the steps of the long division

Ajay bought a fan and a heater for rs 4000. He sold the fan at a profit of a 25% and the heater at a loss of 5%. If he gained 7%
Alborosie

Answer: Heater -Rs 2400; Fan- Rs 1600

Step-by-step explanation:

Given

Ajay bought a fan and a heater for Rs 4000

Suppose the price of fan is x and that of heater is 4000-x

Profit on the fan is 0.25x

Loss on heater is 0.05\times (4000-x)

Total profit is 7% i.e. 0.07\times 4000

\therefore 0.07\times 4000=0.25x-0.05(4000-x)\\\Rightarrow 280=0.25x-200+0.05x\\\Rightarrow 480=0.3x\\\Rightarrow x=1600

Thus, the price of heater is 4000-1600=Rs.\ 2400

Price of fan is Rs.\ 1600

Price of heater is Rs.\ 2400

Which problem could be solved with the expression 4*(4+2)
Rina8888 [55]
The answer is A.

He ran for six (6) miles every day. 4 in the morning and 2 at night = 6 per day.

He did this for four (4) days. The way to figure this would be to go 6 * 4. This equals 24 miles.

Go back a few steps (punny!).

So days multiplied by how many miles he ran a day which is calculated by miles in morning added to miles at night.

days*(miles per morning + miles per night)

days=4
miles per morning=4
miles per night = 2

4 * (4+2)

Calculating this out....

4 * (4+2)

(4+2 = 6)

4 * 6 = 24.

So A is the answer.
