I WILL GIVE BRAINLIEST Hailey is preparing a debate on the benefits of using synthetic polymers over natural polymers, and she wants to create a list to get started.

What of these should Hailey include in her list? (only pick one)

Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.

I would choose biodegradable materials and inexpensive to produce

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answers would be

the first one and the second one
