Answer:
n = -4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
combine like tmers:
6n + 9 = -3n - 27
add 3n to both sides:
9n + 9 = -27
subtract 9 from both sides:
9n = -36
divide by 9:
n = -4
A 3-termed polynomial, also known as a trinomial, is an expression that has terms that cannot be combined. This would mean A and C when simplified. If you have to choose one answer it would be C, but according to the definition of a trinomial, A and C are both applicable as you can add 3 and 4.
Step-by-step explanation:
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find the least common multiple (LCM) of the two denominators.
Answer:
A - Rational
B - Not Rational
C - Not Rational
