A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum:
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs
15^2=9^2+B^2
225=81+B^2
225-81=B^2
144=B^2 (square root both sides)
12=B
5 because these numbers are all equally divisible.
Equation:
(4/(x-2))+(1/((x^2)-4))=(1/(x+2)
Answer:
A: She found one valid solution and no extraneous solutions.
Step-by-step explanation:
When solving you get x= -(11/3)
Asset = 264,000 / 0.75 = $352,000
Shareholders equity = $352,000 - $264,000 = 88,000
Return on equity = 49,280 / 88,000 x 100% = 56%
