serg [7]
X + y = 33
x - y = 9                          Add the 2 equations together
---------------
2x = 42                           Divide both sides by 2
x = 21

Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12

One list had 21 items on it and the other list had 12 items on it.

3. Let the dimensions of the large picture be a (length) by a (width)

4. Area of picture = a^{2}=192  in^{2}

a= \sqrt{192} =   \sqrt{16*12}= \sqrt{16*4*3}=4*2* \sqrt{3}=8\sqrt{3} (feet)

Answer: the dimensions are 8\sqrt{3} (feet) by 8\sqrt{3} (feet)
