3 0

Answer:

No.

Step-by-step explanation:

Take the second expression: 5(2 - 20)

To solve, you must distribute the 5 to all terms within the parenthesis:

5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90

On the other hand:

10 - 20 = -30

∴ the two expressions are not equivalent.

Evaluate the expression:

MAVERICK [17]

Answer:

-70

Step-by-step explanation:

This is not an expression due to the =, because that makes it an equation. So I will assume the = is a +, to make it an expression.

1. Combine all negative numbers: -68 - 4 - 3 = -75

2. Add to 5, -75 + 5 = -70
