The pair of expressions 6(2u+3) and 6n+18 are not equivalent. The pair of expressions 3(2h-5) and 6h-15 are equivalent. The pair of expressions 8(g+2) and 16+8g are equivalent. The pair of expressions 7(2k-4) and 28-14k are not equivalent.
Step-by-step explanation:
The pair of expressions 6(2u+3) and 6n+18 are not equivalent because they have different variables (u and n) and different constant terms. Therefore, they represent different mathematical expressions.
The pair of expressions 3(2h-5) and 6h-15 are equivalent because they have the same variable (h) and the same constant term (-15).
The pair of expressions 8(g+2) and 16+8g are equivalent because they have the same variable (g) and the same constant term (16).
The pair of expressions 7(2k-4) and 28-14k are not equivalent because they have different constant terms (7 and -14) and different variables (k and no variable in the second expression).
The probable question can be: State whether each pair of expressions are equivalent
