Yes they do.
The expression IS 5*4 - 8.
It is: x -5
The expression is: 5(b + x)
"7 = 5 x 2" is a false statement under standard arithmetic rules.
Yes they do.
Yes. Because the x and the 5 can change in same ways.
Yes. Because the x and the 5 can change in same ways.
the order of the factors does not alter the result
Exponential notation is used to represent repeated multiplication of the same factor.
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
When adding, the order does not matter. It's called the summation property.

The expression (x+5)(x-7) = x^2 -2x -35
The expression IS 5*4 - 8.
It is: x -5
The expression is: 5(b + x)
