Write the expression: the product of a number and twelve

• x/12

• x - 12

• 12 + x

• 12x

Find the product: (x + 7)²

• x² + 7x + 7x + 49

• x² + 7x + 7

• 7x² + x + 7

Simplify the expression: -3x²( 7x² - x + 4)

• -21x⁴ + 3x³ -12x²

• 7x² - x + 4 (-3x²)

• 21x⁴ + 3x³ + 12x²

• -12x² + 3x³ -21x⁴
