HELP! I WILL GIVE WHOEVER ANSWERS CORRECTLY BRAINLIEST!! consider the following expression.

9a+5b+4

Select all of the true statements below.

9a + 5b + 4 is written as a sum of three terms.

9a and 4 are like terms.

4 is a constant.

9a is a coefficient.

9a is a factor.

None of these are true.

9a + 5b + 4 is written as a sum of three terms, 4 is a constant, 9a is a coefficient.

Step-by-step explanation:

A coefficient is the number before a letter. In some cases it would be the number you either multiply or divide by another number. A constant is a single number that either isn't changed or is added or subtracted by another coefficient (alone) . A term is just a mathematical expression used in math. It is either just a normal equation or a big expression like this one. You also cant add or subtract 9a by 5b or 4 because in order to to do that 5b or 4 has to have an "a" at the end~example- instead of 5b it would have to be 5a to subtract or add or do whatever . (has to be the same)

i used to know how to do this in 7th but i forget easily
