Work out, you can use your calculator. Remember BEMDAS.

(2⁸)²

• 2¹⁶
• 2¹⁰
• 2⁶
• 2⁴

Classify by number of terms:
3x³ – 6x

• Monomial
• Binomial
• Trinomial
• 4-Term Polynomial

What is the degree of this polynomial?

2x⁴ - 3x⁵ + x

• -3

• 2

• 4

• 5

Simplify the expression.
2x(-2x - 3)

• -4x - 3
• x² - 3
• -4x² - 6x
• -4x - 6

Divide (-20p² - 16p) by -4p

• 5p² - 16p
• 5p + 4
• 5p - 4
• 5p + 4p

Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

Solve the inequality:

4x + 3 < 2x + 1

• x > -1

• x < 1

• x > 1

• x < -1
