Kyra wants to make the area of her rectangular closet 9 times larger than the size it currently is. What scale factor should she use to dilate the dimensions of the closet?
A)Scale factor of 6
B)Scale factor of 12
C)Scale factor of 3
B)Scale factor of 9

choice 3) scale factor of 3

Step-by-step explanation:

3 times length + 3 times width = 9 times area

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
