Final answer:
To simplify (v + 4)(v + 5), use the distributive property to multiply each term.
Step-by-step explanation:
To simplify the expression (v + 4)(v + 5), we can use the distributive property. This property states that for any numbers a, b, and c, (a + b)(c) = ac + bc. So, applying this property here, we can multiply v by v and v by 5, and then multiply 4 by v and 4 by 5. This gives us v^2 + 5v + 4v + 20. Combining like terms, we get the simplified expression v^2 + 9v + 20.
