First do distrubutive property
-(x+4)=-8
Multiply the parenthesis by the invisible -1 in the front
: -x-4=-8
Now add 4 to both sides
-x=-4
then divide -1 by both sides
x=4 is your answer
The answer is 21. 75²=5625 72²=5184 5625-5184=441 √441=21 so 21 is your answer. I hope this helps. The formula to figure out the hypotenuse A²+B²=C² can also be used to find a leg. Since we have one leg and the hypotenuse I was able to figure this out.
9+12>18
12+18>9
9+18>12
So, yes. A triangle can be formed by the given angles.
Answer:
2008
Step-by-step explanation:
M = 48.81t + 304.30
M = 694.78 Solve for t
694.78 = 48.81t + 304.30 Subtract 304.30 from each side
390.48 = 48.81t Divide each side by 48.81
t = 390.48/48.81
t = 8.00 yr
=====
Year = 2000 + t
Year = 2000 + 8.00
Year = 2008
Military spending hit $694.78 billion at the end of 2008.
Sum of interior hexagon = 720
m<D = 720 - (100+115+105+130+95)
m<D = 720 -545
m<D = 175
answer
D. 175
