Answer for the first box is  8

Answer for the second box is 64

===========================================

Explanation:

The expression x^2-16x+64 factors to (x-8)^2. We can see this by FOILing out (x-8)^2 = (x-8)(x-8) to get x^2-8x-8x+64 = x^2-16x+64. You can also use the box method as shown in the diagram below. The box method is a visual way to keep track of the terms. Each cell in the table is the result of multiplying the outer values. Example: the value 64 in row2,column2 is the result of 8*8 = 64. So this shows why 8 goes in the first answer box.

The 64 in the second answer box is from the 64 from step 3. It gets transferred/copied down to step 4.

Charlie Carr has a sheet of brass that is 33 inches wide and cuts two pieces that are each 8
denis-greek [22]

Answer: The width of the leftover brass is 17 inches.

Step-by-step explanation:

Hi, to answer this question, first, we have to add the width of the pieces cut.  

Mathematically speaking:

8 in +8 in = 16 in

Now, we have to subtract that result to the width of the sheet of brass.

33 in -16 in = 17 in

The width of the leftover brass is 17 inches.

Feel free to ask for more if needed or if you did not understand something.
