Final answer:

To multiply the given expression and state the product in simplest form, we need to simplify each expression separately and then multiply the simplified forms.

Step-by-step explanation:

To multiply the expression (k²+7k+12)/(k²+10k+21)*(15)/(3k+12) and state the product in simplest form, we need to simplify each expression separately and then multiply the simplified forms. Here are the steps:

  1. Factor the numerator and denominator of the first expression, (k²+7k+12)/(k²+10k+21), to get [(k+3)(k+4)]/[(k+7)(k+3)].
  2. Cancel out the common factor of (k+3) from the numerator and denominator.
  3. Factor the denominator of the second expression, (3k+12), to get 3(k+4).
  4. Cancel out the common factor of (k+4) from the numerator and denominator.
  5. Multiply the simplified forms: [(k+4)/(k+7)] * (15/3) = (5(k+4))/(k+7).

So, the simplified form of the given expression is (5(k+4))/(k+7).
