Solving Equations Using the Distributive Property

The video tutorial covers simplifying and solving equations, focusing on the use of the distributive property and reverse order of operations (PEMDAS). It provides examples of solving linear equations and translating word problems into equations. Additionally, it addresses solving area and perimeter problems using equations, offering a comprehensive guide to these mathematical concepts.

What must an expression have to be in its simplest form?

• No variables

• Only positive numbers

• Only addition and subtraction

• No parentheses and no like terms

What is the equation for the sum of a number and 8, multiplied by 3, equals 12?

• 3(n + 8) = 12

• 3n + 8 = 12

• n + 8 = 12

• 3(n - 8) = 12

How do you find the area of a rectangle?

• Add the length and width

• Multiply the length by the width

• Divide the length by the width

What is the perimeter of a rectangle with length 3x + 2 and width 2x + 5, if the perimeter is 84 units?

• 84 = 3x + 2 / 2x + 5

• 84 = 3x + 2 - 2x + 5

• 84 = 3x + 2 + 2x + 5

• 84 = 2(3x + 2) + 2(2x + 5)
