Well

4 x 5 = 20
and
5 x 5 = 25
I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:
6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )
So
6 x 7 = 42
There are faster methods but this is probably the best way to start out.

The solution is undefined, the function is parallel. Also the two functions are lunar functions, mx+b=y.
M= slope
B=y-intercept (where it crosses the y-axis)
Step-by-step explanation:
Solutions, colloids and suspensions are the three main classifications of a mixture based on sizes of the particles.
- A solution is a homogeneous mixture of solutes and solvents.
- Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
- Colloids are homogeneous mixtures of two phases.
Solutions have the following characteristics:
- The size of particles is small
- The particles do not settle on standing.
- The particles pass through ordinary filter papers.
- They are clear and do not have color.
- They do not scatter light
Suspensions have the following properties:
- The particles dispersed are large
- They settle on standing.
- The particles do not pass through ordinary filter papers
- They do not pass through permeable membrane
- They are visible with microscope or naked eyes.
- They are cloudy
- Scatters light.
Colloids have the following properties:
- Their particles are between those in solutions and suspensions.
- Their particles do not settle on standing.
- Their particles pass through ordinary filter paper.
- They do not pass through permeable membranes.
- Scatters light
