9plus 3 over x divided by x over 4 plus 1 over 12 equals ?

36/x

Step-by-step explanation:

(9+3/x) / {(x/4)+(1/12)}

{(x/4)+(1/12)} = (3x+1)/12

(9+3/x)  = (9x+3)/x

(9+3/x) / (3x+1)/12

(9x+3)/x /(3x+1)/12

((9x+3)/x ) . (12/(3x+1))

12(9x+3) / (x(3x+1)

108x+36 / 3x² + x

36(3x+1) /(x(3x+1)

3x+1 cancels each other

36/x

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

pi x^2

step-by-step explanation:

pi times x squared
