Evaluate each expression. Name the property used in each step

5 ( 14 - 39 ÷ 3) + 4 • 1/4

6

Step-by-step explanation:

5 ( 14 - 39 ÷ 3 ) + 4 ×

= 5 ( 14 - 13 ) + 4 × (Division Property)

= 5 ( 1 ) + 4 × (Subtraction Property)

= 5 + 1 (Multiplication Property + Simplified)

= 6 (Addition Property)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
