-6x + 12
To find this answer, follow these steps:
First, multiply 2x + 3 and x - 6 using either the FOIL method or the box method. This should get you the answer of 2x^2 - 9x - 18
This should now replace the 2x + 3 and x - 6
So with that, you should have this currently:
2x^2 - 9x - 18 - 2x^2 + 3x + 30
Now, combine like terms:
The 2x^2 cancels each other out. After that, combine -9x and 3x to get -6x. Then -18 and 30.
This should leave you with the final answer of -6x + 12
Hope this helps!
Here is the answer in comma-separated list.

You need 5 dimes while having 10 or 25
Area = 285mm²
Length = 18mm
We can find the width by dividing the area by the length.
approximately.
2(18) + 2(15.8) = 67.6mm

The smallest number of students in the class is the smallest number that is divisible by 2, 3, and 4. You need the least common multiple of 2, 3, and 4.
This is like finding the least common denominator.
Find the prime factors of the three numbers:
2 = 2
3 = 3
4 = 2^2
To find the LCM you need common factors, and not common factors with the larger exponent.
Now single factor is common to all numbers.
There is 2 and 2^2, so use 2^2 since it has the larger exponent.
There is also a 3, so use the 3.
LCM = 2^2 * 3 = 4 * 3 = 12
Mr. Carson's class may have 12 students. 12 is the smallest number of students it can have.
