Perform the indicated operation. x^2-y^2/3x*3y/x+y

x^2 - y^3 + y

Step-by-step explanation:

Simplify the following:

x^2 - (3 y^2 x y)/(3 x) + y

-(y^2 x×3 y)/(3 x) = 3/3×(-y^2 x y)/x = (-y^2 x y)/x:

x^2 + -(y^2 x y)/x + y

(-y^2 x y)/x = x/x×-y^2 y = -y^2 y:

x^2 + -y^2 y + y

-y^2 y = -y^(2 + 1):

x^2 + -y^(2 + 1) + y

2 + 1 = 3:

 x^2 - y^3 + y

i got 142 as my answer

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
