Since both terms are perfect squares factor the denominator:
answer is <span>C. m²/(m + n)(m - n)</span>
Answer:
-5+5r-2 -->
--> 5r-7 <--
Explanation --
Distribute from the parentheses, of course excluding the -2 because it isn't involved, and you'll get --> -5 + 5r -2
Simplify by putting the like terms together (subtract) -->
5r -7 (you get -7 by doing -5-2, and you leave 5r by itself since it doesn't have anything more to simplify with or has any other like term)
So, the final, simplified answer -->
5r-7
Hope this helps!! Have a nice day! :)

Distribute

Combine like terms

Add 1 and subtract 6x from each side
0 = 12
The equation has no real solution
Answer:
Step-by-step explanation:
8:60 is the rate
Divided by 2
4:30
So, she could run 4 kilometers in 30 minuets.
Divide by 2 again.
2:15
