Answer:
Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:
Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":
Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:
The answer is A, or 40.82 ft. This can be found using the formula for finding the perimeter of a circle: 2pir (2 x pi x radius). 2 x 3.14 = 6.28, and 6.28 x 6.5 = 40.82 ft. Hope this helps!
Value of y= 18 and value of x= 9 root3
therefore answer is D
12-13 I hope this helps ;)
Subtracting a negative number is the same as adding a positive number
assume your number is n
n - (-10) = 6
n + 10 = 6
subtract 10 from both sides
