Final answer:

The product of (x+3)(x + 4) is x² + 7x + 12.


Step-by-step explanation:

The product of (x+3)(x + 4) can be found by multiplying each term in the first parenthesis by every term in the second parenthesis and then combining like terms. Using the distributive property, we have:

(x+3)(x + 4) = x*1 + x*4 + 3*1 + 3*4 = x^2 + 4x + 3 + 12 = x^2 + 7x + 15.

Therefore, option b. x² + 7x + 12 is the correct product.
