So first we start off multiplying 3 • 7 to find a common denominator and you get 21. Then because you technically multiplied 3 by 7 you also have to multiply 1 by 7! you instead of 1/3 you have 7/21! do the similar thing to 2/7 but instead of multiplying it by 7 you use 3 so for this one instead of 2/7 it’s 6/21! add the two fractions together and get 13/21! subtract 13 from 21 to see what the remaining fraction is and your answer is 8/21! hope this helps!!

Answer:
7)no
Step-by-step explanation:
When you plug in the numbers
3(2)-0=-6
6-0=6
6 does not = -6
We know that
The triangle inequality<span> states that for any </span>triangle, t<span>he sum of the lengths of any two sides of a </span>triangle<span> is greater than the length of the third side
</span>so
case <span>A. 81 mm, 7 mm, 6 mm
6+7 is not > 81
case </span><span>B. 81 mm, 7 mm, 72 mm
72+7 is not > 81
case </span><span>C. 81 mm, 7 mm, 88 mm
81+7 is not > 88
case </span><span>D. 81 mm, 7 mm, 77 mm
81+7 is > 77------> ok
77+7 is > 81-----> ok
81+77 is > 7-----> is ok
the answer is the option
</span>D. 81 mm, 7 mm, 77 mm
