Question

If $5$ is added to three times the product of numbers $m$ and $n.$

Express the above statement as an algebraic expression.

• A. $5(mn+3)$
• B. $3(mn+5)$
• C. $(3mn+5)$
• D. $(3m+n+5)$

Answer 1

The correct option is C $(3mn+5)$

Product of $m$ and $n=m\times n=mn$

$3$ times the product of $m$ and $n=3\times mn=3mn$

$5$ is added to $3$ times the product of $m$ and $n=3mn+5$

Three times the product of numbers m and n can be written as $3\times m\times n=3mn$.
Therefore, addition of $5$ to three times the product of numbers $m$ and $n$ can be written as $3mn+5$.
