2. The side lengths of a square measure 25.3 cm. Estimate the area of the square.
about 25 sq. ft.
about 50 sq. ft.
about 500 sq. ft.
about 625 sq. ft

625 sq ft.

Step-by-step explanation:

25 cm is close to 25.3 so our estimate is 25 * 25 = 625.

b

step-by-step explanation:

  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.
