the circumference is about 18.85
<span> the answers are ...C. 16x – 4 and D. 4(4x – 1) ...
Hope it helps !!!</span>
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.

Answer:
7 cm, 4.4 cm
Step-by-step explanation:
The side lengths can be found from the law of cosines. Each triangle has legs 3 cm and 5 cm. The angle between these will be 60° or 120°. Then the two sides of the parallelogram are ...
s = √(a² +b² -2ab·cos(C))
s = √(3² +5² -2·3·5·(±1/2)) = √(34 ±15) = {√49, √19}
The two side lengths are 7 cm and about 4.4 cm.
