Jennifer and Callie are training for a marathon. Jennifer has run m miles, and Callie has run 3 times as many as Jennifer. The expression shows how many miles they have run altogether.

Question

m + 3m

Which of the following expressions could be used to get the same results?
A.
4m2
B.
4m
C.
m + 3
D.
m + 4

Answer 1

To find the expression that gives the same results as \( m + 3m \), we first simplify \( m + 3m \):

\[ m + 3m = 4m \]

Now, we need to determine which of the provided options matches \( 4m \):

A. \( 4m^2 \) – This is not the same as \( 4m \). B. \( 4m \) – This is the same as \( 4m \). C. \( m + 3 \) – This is not the same as \( 4m \). D. \( m + 4 \) – This is not the same as \( 4m \).

The correct option that could be used to get the same results is:

B. \( 4m \)
