Answer:
D.
Step-by-step explanation:
We have been given 4 expressions. We are asked to choose a trinomial with a leading coefficient of 3 and a constant term of -5.
Let us check our given choices one by one.
A.
Upon looking at our expression, we can see that leading coefficient is and constant term is 3, therefore, option A is not a correct choice.
B.
Upon looking at our expression, we can see that leading coefficient is 3 and constant term is . But we can see that this expression is not a trinomial as it has only two terms, therefore, option B is not a correct choice.
C.
Upon looking at our expression, we can see that leading coefficient is 3 and constant term is 1 . Therefore, option C is not a correct choice.
D.
Upon looking at our expression, we can see that leading coefficient is 3 and constant term is and expression has three terms. Therefore, option D is the correct choice.
