Multiple Choice

Classify the following polynomial:  $$x^2+5x-2$$  

• Monomial

• Binomial

• Trinomial

Multiple Choice

Identify the leading coefficient:  $$x^2+5x-2$$  

• 1

• 5

• -2

Multiple Choice

What would be the best first step?

$$5\left(x+6\right)=2x-3$$  

• Distribute the 5.

• Combine the 2x and 3.

• Combine the x and 6.

• Subtract 2x on both sides.

Multiple Choice

Use the inequality to answer the following question. 

$$-2\left(5x-3\right)\ \le14$$  

Which of the following inequalities could be the result of the first step in solving the inequality for x?

• $$5x-3\ge-7$$  

• $$5x-3\le16$$  

• $$-10x-3\le14$$  

• $$-10x+6\le14$$  

Multiple Choice

Which of the following statements BEST describes how to get from Step 2 to Step 3?

2(4x + 8) + 3x = 12

Step 1:     8x + 16 + 3x = 12

Step 2:           11x + 16 = 12

Step 3:                  11x = -4

Step 4:          x = $$-\frac{4}{11}$$  

• Associative Property of Addition
