Measuring

(m + n)² can be expressed as 

• m + n²

• 2 (m + n)

• m² + n²

• (m + n) (m + n)

Which of the following is true?

• (a-b)² = a² - b²

• (a + b)² = a² + 2ab + b²

• (a - b)² = a² - 2ab - b²

• (a + b) (a - b) = a² - 2ab + b²

(a + b)²

• a² + 2ab + b²

• a² - 2ab + b²

• (a + b) (a – b)

Do you add, subtract, multiply or divide the sides to find perimeter?

• add

• subtract

• multiply

• divide
