Answer 2

To solve this expression, we need to apply the distributive property of multiplication and then simplify the result.

7(x+4)(x+5) = 7(x^2 + 5x + 4x + 20) [apply the distributive property]

= 7(x^2 + 9x + 20) [combine like terms]

= 7x^2 + 63x + 140 [multiply 7 by each term inside the parentheses]

Therefore, the simplified expression is 7x^2 + 63x + 140.
