The answer should be x/x^2-2x. Then you have to simplify by x since there has a common unknown in the numerator and the denominator. So use x to divide the numerator and denominator. The final answer is 1/x-2
The main formula is
M= P (i(1+i)^n) / <span>(1+i)^n) - 1
M: monthly payment
P: mortgage principale= </span><span> $20,230
i=montly interest, 11.5%=11.5/100=0.115, i= 0.115/12=0.009
n=number of months=12x20(years)=240 months
M= </span>$20,230(0.009(1.009)^240) / (1.009)^240-1=<span>$20,230 x 0.0077 / 8.58-1
M=$20.57

Goes up by 4’s believe the first question is 41
∠AXY=∠XBC=55°(corresponding angles)
XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°
The sum of all the angles in a triangle is 180°⇒
55°+55°+∠BXC=180°
∠BXC=70°
