Help please I don't understand!!!
shusha [124]
A- 2b = 2  one of the 2 "A" most be negative so they can cancer each other 
-a- b = 6   after the "A" cancel each other add the -2b with -b = -3b, then add 2 
--------------    and 6 
    -3b=8    then you have to divide 8 by -3 = -2.6       -2.6 its b... now you have to solve for b       step  1.  a -2b = 2   step 2.   a -2(-2.6)=2     step 3   a -5.3 = 2  then subtract -5.3 with 2 so that going to be 2 + 5.3 =7.3 then divide by a 
final answer (-2.5,-7.3)
sorry its kinda hard to explained here, i hope you get the point :)

A square mosaic is made of small glass squares. If there are 196 small squares in the mosaic, how many are along an edge?
alexandr402 [8]
There would be 14 small glass squares along the edges of the square mosaic.  

This is because 14 * 14 = 196, which means that if each side length was 14 squares, that the area of the square would contain 196 squares.
