Mr. thaxton has two daughters. the sum of their ages is twenty-one. the product of their ages is one hundred ten. how old is mr. thaxton's youngest daughter?

a.
9

b.
10

c.
11

d.
12

B. 10

Step-by-step explanation:

x + y = 21

xy = 110

Rewrite first equation. x + y = 21 becomes y = -x + 21

Now substitute this new equation in the second equation.

x(-x+21) = 110

-x^2 + 21x - 110

Divide by -1

x^2 - 21x + 110

(x - 10)(x - 11)

x = 10, 11

10 is less, so the youngest daughter is 10
