Answer:
12 years younger.
Step-by-step explanation:
Let Jan's age be J and Karyn's age be K.

Jan's age 8 years ago is 2/5 of Karyn's age 4 yeaRs from now.

=> 
=> 4K = 48 X 3
=> K= 36.
=> J= 24.
So Jan is 12 years younger.
The x and y axis so that’s why it’s true

Given the surface area of the sphere, for us to obtain the volume we need to get the value of the radius. The surface area of the sphere is given by:
S.A=4πr^2
hence the radius can be calculated as follows;
16=4πr^2
4=πr^2
r=(4/π)^(1/2)
volume of a sphere is given by:
V=4/3πr^3
=4/3*π*(4/π)^(1/2))^3
=32/3 cubic inches
For this case we have the following polynomial:

To find the value of c that completes the square, we use the following equation:

Where,
- <em>b: coefficient of the variable of degree 1
</em>
Substituting values we have:

Answer:
the value of c that completes the square is:
