Question

Which pair shows equivalent expressions? (Look at picture)

Answer 1

Answer:

-2x - 10 = -2(x + 5)

Step-by-step explanation:

-2x - 10 is already simplified, but in order to understand the solution, we need to simplify -2(x + 5) in order to show that it is an equivalent expression:

-2(x + 5) = -2x - 2(5)

Further simplify:

-2x - 10

This proves that -2x - 10 = -2(x + 5) is an equivalent expression.
