Question

Tena is five years older than her sister Tammy. The product of their ages is 234. How old is Tammy?

Answer 1

a..12 b. 10 c. 13 d. 24

Answer 2

Tammy's age is \(x\), and Tena's age is \(x+5\).
We know that \(x\cdot(x+5) = 234\).

Answer 3

This will simplify to: \[
x^2+5x-234 = 0
\]You can solve this like any other quadratic equation.

Answer 4

Still figuring it out. i almost got it.

Answer 5

Is Tammy 13? Because I took 13 * 18 and that equaled 234.

Answer 6

If that worked, then yes.

Answer 7

Did you guess, or did you solve it with algebra?

Answer 8

I solved it by taking the four answers I had and added the 5 years to each and then just multiplied them.

Answer 9
