What two numbers add up to 10 and multiply to 21

Mathematics
1 answer:
WITCHER [35]3 years ago
3 0

Answer:The answer is 3 & 7

Step-by-step explanation:3 x 7 = 21

3 + (7) = 10

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 + 10x + 21 = 0

If so, the solution to factor the quadratic equation above is:

(X + 3 ) (X + 7)

To summarize, since 3 and 7 multiply to 21 and add up 10, you know that the following is true:

x2 + 10x + 21 = (X + 3 ) (X + 7)

Fofino [41]

Answer:

The net cash provided by investing activities is $90,000

Step-by-step explanation:

In this question, we are asked to calculate the net cash that is provided by investing activities.

To calculate the net cash provided by investing activities, we simply subtract the cash used to purchase equipment from cash from sale of land.

Mathematically, net cash provided by investing activities = cash from sale of land - cash used to purchase equipment.

From the question, we can identify that cash from sale of land is $150,000 while cash used to purchase equipment is $90,000

We substitute these and get; $150,000 -$60,000 = $90,000

Points N and R both lie on circle O. Line segment RQ is tangent to the circle at point R.
ANEK [815]

Answer:

Perimeter ΔRON = 18.66 units

Step-by-step explanation:

Complete Question has these information given as well:

  • Circle with center O
  • RN = QN
  • RQ = 5\sqrt{3}
  • ON = 5 units
  • RQ is tangent

<em><u>Now, we draw an image according to the information given. THe image drawn is attached.</u></em>

<em><u /></em>

Looking at the figure, we can say the perimeter of triangle RON would be:

RON = OR + ON + RN

We know according to tangent theorem, QN = QR

RN is equal to that as well and RN = 5\sqrt{3}

Now,

OR and ON is the radius, which is "5"

Perimeter of RON = 5 + 5 + 5\sqrt{3} = 10 + 5\sqrt{3} = 18.66 units

<u>Perimeter ΔRON = 18.66 units</u>
