Step-by-step explanation:
4x+5+3x-2=31
7x+3=31
7x=28
x=4
Do the rainbow method
x^2 - 6x + 2x - 12
Now simplify
x^2 - 4x - 12
The answer is x^2-4x-12
213
A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 213 can be evenly divided by 1, 3, 71 and 213, with no remainder. Since 213 cannot be divided by just 1 and 213, it is a composite number.(I think I got this from the internet so I'm not sure)
