Answer:
Option B. ( xy + 3x + 8y + 24 )
Step-by-step explanation:
In this question we have to find the product of the given expression
(x + 8) (y + 3)
By distributive property.
(x + 8) (y + 3) = x (y + 3) + 8 (y + 3)
= x (y) + 3x + 8y + 3 × 8
= ( xy + 3x + 8y + 24 )
Therefore, Option B. ( xy + 3x + 8y + 24 ) is the correct answer.
