(y^2+y)(3y^2-2y^3)=y^2(3y^3-2y^3)+y (3y^3-2y^3) is an example of ?

the correct answer is, The distributive property

B) the distributive property

Step-by-step explanation:

In the distributive property, everything within a group (set of parentheses) is multiplied by the term (or terms) outside parentheses.

In this case, we are multiplying everything in the second group first by y²; then we multiply everything in the second group by y.

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

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35
