Final answer:
To distribute the minus sign outside the parentheses, you need to multiply each term inside the parentheses by -1. The equivalent expression is -16u + 20v.
Step-by-step explanation:
To distribute the minus sign outside the parentheses, you need to multiply each term inside the parentheses by -1. In this case, the expression inside the parentheses is -1 times 4(4u-5v).
Step 1: Distribute the -1 to each term inside the parentheses.
-1 * 4(4u-5v) = -4(4u-5v)
Step 2: Simplify the expression.
-4(4u-5v) = -16u + 20v
