    SOLUTION: If the sum of two numbers is 19 and their product is 90, what is the sum of their squares? sum of two number is 9 + 10 = 19 product is 9 x 10 = 90 9^2 + 10^2 = 181

    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!

    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

    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
