If Ann correctly factors an expression that is the difference of two perfect squares, her factors could be 1) (2x + y) (x - 2y)
2) (2x + 3y) (2x - 3y)
3) (x-4)(x-4)
4) (2y - 5) (y - 5)

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

answer: can you give the
