12 and 7

Step-by-step explanation:

Here are your equations:

x + y = 19

xy = 84 OR 2xy = 168

First we have to square the first equation. That is x² + 2xy + y² = 361.

We can substitute the second equation for 2xy and we get x² + y² = 193

We can now solve for x and y which is 12 and 7.

Hope this helps!

15 and 4 15+4=19 15×4=60

15 and 4

15+4= 19

15×4= 60

7 and 12

Step-by-step explanation:

Define x:

Let one of the number be x

The other number is 19 - x

Solve x:

Their product is 84

x (19 - x) = 84

19x - x² = 84

x² - 19x + 84 = 0

(x - 7) (x - 12) = 0

x = 7 or x = 12

When x = 7, the other number is 19 - 7 = 12

When x = 12, the other number is 19 - 12 = 7

⇒ The numbers are 7 and 12

The numbers are 7 and 12

sorry po kasi di ko maintindihan yung answer nag calculator sana ako pero ayaw ma kuha

answer:

What do you mean by finding the product? But if you're asking about the two numbers they are 15 and 15×4= 60 15+4=19

answer:

you already give the answer
