Question #3dc52

Answer 1

The answer is `-5a+14.2`, or `14.2-5a`.

Explanation:

`8+4a+6.2-9a`

Gather like terms.

`4a-9a+8+6.2`

Simplify.

`-5a+14.2` `larr` `color(red)("Try this instead")`.

This can also be written as:

`14.2-5a` `larr` This means the same as `-5a+14.2`, but maybe the computer program wants it the other way. If it's still incorrect, contact your teacher.
