x = 10

Step-by-step explanation:

Lets start it off

BD/BA = EC/CA is what you are going to need

so 6 / 15 = x / 25 then you cross multiply

150 = 15x then you divide each side by 15 and you get

10 = x or x = 10

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

a rhombus is a parallelogram enjoying his symmetry.
