Arectangular yard measures 8 m by 6 m. what happens to the area if each dimension is doubled?
a. it becomes four times smaller
b. nothing
c. it becomes twice as large
d. it becomes three times greater
e. none of the above

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Graph a should be your answer
