I think this is how you solve this and the answer <span><span><span>0.1+30</span>+8</span>−12</span>+<span>14</span><span>=<span>26.35

<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
</span>
Yes , taking root on both sides we have y = √(4-x^2) so y is dependant on x and x only..so y is a function of x .
Let x represent the number:
2/3(x)+15=9
2/3(x)= -6
x= -6/(2/3)
x= -6*(3/2)
x= -9
