Question

1. $24m + 31n$ and $8(3m + 4n)$

Explanation:

Step1: Expand the second - expression

$8(3m + 4n)=8\times3m+8\times4n = 24m+32n$

Step2: Compare the two expressions

We have $24m + 31n$ and $24m+32n$. Since the coefficients of $m$ are the same in both expressions, but the coefficient of $n$ in $24m + 31n$ is $31$ and in $24m+32n$ is $32$, the two expressions are not equal.

Answer:

The expressions $24m + 31n$ and $8(3m + 4n)$ are not equal.
