1.                              2. –3(2x – 5) = 7 – 4(x – 6)                         3.  If x=–5 and y=3,

                                                                                                                           find the value of x2 – y2.

 

 

 

4. The perimeter of a rectangle                                         5.   A box contains $8.70 in quarters and

     is 700 meters. The length is                                                dimes. There are a total of 42 coins.

    10 less than twice the width.                                                 How many of each are there?

    Find the length and width.

 

 

 

 

6. Solve for x, and graph:                                                     7.    Multiply: (3x – 5)2
