Answer:
The answer is B.
Step-by-step explanation:
You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :

Let a = 40,
Let b = 9,





*Take note, hypotenuse will <u>a</u><u>l</u><u>w</u><u>a</u><u>y</u><u>s</u><u> </u><u>b</u><u>e</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>l</u><u>o</u><u>n</u><u>g</u><u>e</u><u>s</u><u>t</u><u> </u><u>l</u><u>e</u><u>n</u><u>g</u><u>t</u><u>h</u> among the 3 lengths.
*Pythogorean Theorem can only applied in a right-angle triangle.
Answer:

Answer:
I think is -x + 105/42y
Step-by-step explanation:
2(3/10)x - 5/7y - 4(5/6)y - 2(4/5)x
6/10x - 5/7y - 20/6y - 8/5x
6/10x - 8/5x - 5/7y - 20/6y
6-16/10x - 35+140/42y
-10/10x + 105/42y
-x + 105/42y
2.8 because 14/5 equals 2 80/100.
