    Question 1

    3y; y+y+y

    3y = 3 (2) = 6

    y+y+y = 2+2+2 = 6

    anwser: They are both 6.

    Question 3

    2z+3z

    answer: 5z

    part 2

    2z+3z

    Evaluate the expression when z=7.

    2 (7) + 3 (7) = 14 + 21 = 35

    Question 4

    Consider the expressions 6x and 3 (x+2).

    Evaluate each expression for x=2.

    6x = 6 (2) = 12

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

    answer:

    The expressions are not equivalent, but the answers are the same when x=2.

    Question 7

    Select all the statements that are true.

    _F__ 116b is equivalent to 16b.

    _F__ 14b+13b is equivalent to 27b.

    __F_ 13 (b+7) is equivalent to 13b+73.

    _T__ b+0.3+4b is equivalent to 5b+0.3.

    Question 8

    Select all the statements that explain why 7x+2x and 4x+5x both equal 18 when x=2.

    7x+2x = 7 (2) + 2 (2) = 14 + 4 = 18 ... (9x)

    and

    4x+5x 4 (2) + 5 (2) = 8+10 = 18 ... (9x)

    Answer:

    ___ Both expressions simplify to 9x when like terms are combined.

    ___ The expressions are equivalent, because when you combine like terms in each, the result is the same.

    Question 10

    Consider the expressions 2 (x+2) and 2x+2.

    Evaluate each expression for x=4.

    2 (x+2) = 2 (4+2) = 12 ... (2x+4)

    2x+2 = 2 (4) + 2 = 10 ... (2x+2)
