Question

Which expressions are equivalent to [-2(2h 10) 4h]?

1) [-20-4h 4h]
2) [-20]
3) None of the above

Answer 1

The expression [-2(2h+10) + 4h] simplifies to -20.

Step-by-step explanation:

The expression [-2(2h+10) + 4h] can be simplified using the distributive property and combining like terms. Here are the steps:

1. Apply the distributive property to -2(2h+10) and simplify: -2 * 2h + -2 * 10 = -4h - 20
2. Combine like terms by adding the terms with 'h': -4h + 4h = 0h

Therefore, the equivalent expression is 0h - 20, which can be simplified to just -20. So the correct answer is 2) [-20].
