Public communication because one person is talking to an audience, and it's not big enough to be mass communication. And it's not group because that consists of three or more communicating a shared goal. Also isn't it because interpersonal is a talking between two people.
Answer:
You call an expression with a single term a monimial, an expression with two terms is a binomial and an expression with three terms is a trinomial. An expression with more than three terms is named simply by it's number of terms. For example a polynomial with five terms is called a five-term polynomial.
Step-by-step explanation:
18 students are 1/10 of the number of seventh graders
First choice.
2 - 3d = 4d - 19
Add the opposite to both sides to get the variable on the left side only.
2 - 3d = 4d - 19
-4d -4d
2 - 7d = - 19
Then get the terms w/o variables on the right,
2 - 7d = - 19
-2 -2
-7d = -21
Then divide by the number paired with the variable.
--7d = -21
----- ----- ; d = 3
-7 -7
Final answer = 3
