Question

why would it be difficult to model the equation 12m + 40 = 460 without algebra tiles? because the equation is too complex; because it requires a large number of tiles; because algebra tiles cannot represent variables; because the equation has no solution

Explanation:

First, eliminate incorrect options: the equation is a simple linear equation, so it is not "too complex"; algebra tiles can represent variables; the equation has a valid solution ($M=35$). The large constants (40 and 460) and coefficient 12 would require a very large number of individual tiles to model physically, making it impractical.

Answer:

B. Because it requires a large number of tiles
