What is the correct expression for the perimeter of the triangle?

• x+10

• 3x+10

• $x^2+6+4$

• y=10x+3

What is the correct expression to represent the the perimeter of the above rectangle?

• 2x-2

• 2x-4

• 4x-4

• 4x-2

What is the first step to solving a linear equation?

• Simplify the answer.

• Check to see if you can combine like terms.

• Take the variables out of the equation.

• Check to see if you need to do the distributive property.

What does it mean to have a number and a variable together?

For example: 3x

• Add

• Drop the x.

• Multiply

• Subtract

What do I need to do first to solve the following linear equation?

3x+4+x=6x

• Get rid of the x's.

• Combine 3x, x, and 6x

• divide both sides by 3.

• Combine 3x and x on the left side.

What could I do first to solve the following equation?

(Select all that apply)

3(2x+5)=6+3(x-2)

• Divide both sides by 3.

• Distributive property on both sides.

• Add two to both sides.

• Combine 6 and 3 on the right side.
