Which expression is equivalent to m − 20? (4 points)
(m − 4)
(m − 100)
5(m − 4)
5(m − 100)
Which expression is equivalent to m − 20? (4 points)
(m − 4)
(m − 100)
5(m − 4)
5(m − 100) NONE of them are equivalent to m - 20
To elaborate, start by noting that m−20≠m−4≠m−100 since the constants are different. Use the distributive property on the last 2 equations, which gives 5(m−4)=5(m)+5(−4)=5m−20, which is not equivalent to m−20, and 5(m−100)=5(m)+5(−100)=5m−500, which is also not equivalent to m−20. Thus none of the expressions are equivalent to m−20.
Is there not a shortcut for LaTeX?
