Simplify the following rational expressions.
a. (1 / y − 1 / x) / (x / y − y / x)
b. (1 / x + 1 / y) / 1 / x^2 − 1 / y^2)
c. (1 / x4 − 1 / y2 )/ (1 / x4 + 2 / x2y+ 1 / y2)
d. (1 / x − 1 − 1 / x) / (1 / x − 1 + 1 / x)

the solution is h=10 because you add 9 to each side of the equation.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
