The Johnson twins were born four years after their older sister. This year, the product of the three siblings ages is exactly 34

svp [43]

Answer:

Step-by-step explanation:

Let age of each twin be x

let age of sister be s

So we can write:

x + 4 = s

The product of the 3 siblings ages is 3482 more than sum. We can write:

$s*x*x=3482+(s+x+x)$

This can be simplified as:

$sx^2=3482+s+2x$

We replace s with "x + 4" and solve:

$(x+4)x^2=3482+x+4+2x\\x^3+4x^2=3486+3x\\x^3+4x^2-3x-3486=0\\x=14$

Note: To solve this cubic, we used technology

Thus, we can say the twins are 14 years old
