Answer: -19x
Step-by-step explanation: In this problem, we're asked to simplify the expression.
The two parts of this expression, -8x and 11x are called terms. The numbers in front of the variables are called coefficients.
Because the variables, x and x are identical, the terms get a special name and they're called like terms.
To subtract like terms, we simply subtract their coefficients and add the variable on to the difference of the two numbers.
Since -8 (-11) is -19, -8x - 11x simplifies to -19x.
The answer is x = 62. YOU'RE WELCOME :D

Answer:
28,449,792,000
Step-by-step explanation:
There are 8P5 = 6720 ways the five students who sit on the front row can arrange themselves.
There are 8P4 = 1680 ways the four students who sit on the back row can arrange themselves.
In the remaining 7 seats, there are 7P5 = 2520 ways the remaining 5 students can arrange themselves.
The total number of possible arrangements of students (with the given limitations) is ...
6720·1680·2520 = 28,449,792,000
_____
nPk = n!/(n-k)!
so 8P5 = 8!/3! = 8·7·6·5·4 = 6720
