Answer:
2m−7n
Step-by-step explanation:
Let's simplify step-by-step.
6(m−2n)−(4m−5n)
Distribute the Negative Sign:
=6(m−2n)+−1(4m−5n)
=6(m−2n)+−1(4m)+−1(−5n)
=6(m−2n)+−4m+5n
Distribute:
=(6)(m)+(6)(−2n)+−4m+5n
=6m+−12n+−4m+5n
Combine Like Terms:
=(6m+−4m)+(−12n+5n)
=2m+−7n
The square root of 26 is 5.0999... which rounds to 5.1
