Question

Use the distributive property to simplify the expression below:
The quantity of 3 times x minus 21 all divided by 3

Answer 1

\[\left( 3x -21 \right) \over 3\]?

Answer 2

Is this the expression you mean?

Answer 3

Yes.

Answer 4

ok... write \(\Large \frac{3x-21}{3} \) as \(\Large \frac{1}{3}(3x-21) \) so you can distribute the 1/3 to the parenthesis...

Answer 5

but i think it would be better to simplify the expression by factoring the numerator as 3(x-7) and cancel common factors from numerator/denominator...
