Find the value of the expression 6xy − 3xy, when x = 3 and y = 4

The expression 6xy - 3xy can be simplified to 36 if x = 3 and y = 4.

Step-by-step explanation:

First let's simplify the problem.

6xy - 3xy = 3xy

3xy

Now let's substitute x for 3 and y for 4.

3 x 3 x 4

Finally, let's solve using the associative property!

  (3 x 3) x 4

= 9 x 4

= 36

  3 x (3 x 4)

= 3 x 12

= 36

The expression 6xy - 3xy can be simplified to 36.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
