Nine times the sum of a number and three

• 9 ( 3x )

• 9 ( x + 3 )

• 9 ( x - 3 )

• 9x (3)

Translate the sentence into an equation.
Seven subtracted from n is 18 

• n + 7 = 18
• 7 - n = 18
• n - 7 = 18
• n + 7 = 18n

If 16 is subtracted from twice the square of an integer, the result is equal to eight times the integer. What is the value of the integer?

S = 3F - 24  Solve for F

• F = (S + 24)/3
• F = S/3 + 24
• F = 3S + 24
• F = 3(S + 24)

When completing the square

x² - 4x + 4 = 20, what goes in the blank? (x - __ )² = 20

• 4
• 2
• 8
• 20

Complete the Square
x² - 12x

• (x + 6)² + 12
• (x - 6)² - 24
• (x - 6)² - 12
• (x - 6)² - 36

Factor the perfect square trinomial
x² + 14x + 49

• (x+7)²
• (x+7)(x-7)
• (x-7)²
• (x+14)²

Factor the perfect square trinomial:
x² + 16x + 64

• (x+8)²
• (x-8)²
• (x-4)²
• (x+4)²
