Answer:
B. [tex] -3x [/tex]
Step-by-step explanation:
In algebra, a term could be a single negative or positive number (constant), a variable or a variable with a coefficient. It could also be 2 variables multiplied together.
The algebraic expression [tex] -3x - 7(x + 4) [/tex] , can be expanded and expressed as:
[tex] -3x - 7(x) -7(+4) [/tex]
[tex] -3x - 7x - 28 [/tex]
The three terms are: [tex]-3x, - 7x, -28[/tex]
Therefore, from the given answer choices, the term that is a term in the expression, [tex] -3x - 7(x + 4) [/tex] , is B. [tex] -3x [/tex]
