  2y^6 +12y^4 +5y^3 +30y

Step-by-step explanation:

Given:

  rectangle height: 2y^3 +5

  and width: y^3+6y

Find:

  the area as a polynomial

Solution:

  The area is the product of height and width:

  A = (2y^3 +5)(y^3 +6y)

  A = (2y^3)(y^3 +6y) +5(y^3 +6y)

  A = 2y^6 +12y^4 +5y^3 +30y . . . . area of the rectangle

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
