The answer is 5(6 w+4)
To expand the expression 5(3w^2 + 4), you need to distribute the 5 to both terms inside the parentheses. This means that you multiply the 5 by each term individually.
Let's apply the distributive property:
5 * 3w^2 = 15w^2
5 * 4 = 20
So, expanding the expression gives you:
5(3w^2 + 4) = 15w^2 + 20
