Answer:

$\\ \frac{2}{3} - \frac{1}{4} + \frac{( - 5)}{6}$

$\\ = \frac{2}{3} - \frac{1}{4} - \frac{5}{6}$

$\\ = \frac{8 - 3 - 10}{12}$

$\\ = \frac{8 - 13}{12}$

$\\ = \frac{ - 5}{12}$

Find the dimensions of a rectangular prism whose volume is (x^4 ‒ y ^4) units3.

vovikov84 [41]

Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length), (x+y) (width), and (x-y) (height)
