2xy=2*3*5= 30
It essentially means 2(3)(5) so you just multiply it all together.

ANSWER

The three expressions are

$V = 2(9 - {b}^{3} )(9 + {b}^{3} )$

EXPLANATION

We were given the volume in cubic units to

$V = 162 - 2 {b}^{6}$

If we factor 2, we get,

$V = 2(81 - {b}^{6} )$

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

$V = 2( {9}^{2} - ({b}^{3})^{2} )$

This further gives us.

$V = (2)(9 - {b}^{3} )(9 + {b}^{3} )$

To motorists leave from the same point at the same time, one traveling east at 36 MPH and the other traveling west at 44 MPH. Ho

Ber [7]

This is a very good question to know about. People who make tests really like it.

The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.

The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???

t = d/r
t = 260/8
t = 32.5 hours.

Thats 32 1/2 hours.
