The degree of the polynomial 2x + 5 is 1. The highest power of x is x1, i.e. 2x1 + 5x0, hence the designation of first degree.
C 5 2 = 5! / (2! x 3!) = (5x4x3x2x1) / (2x1 x 3x2x1) = 10
(x + 4) + (x + 5) = 2x + 9
(x + 4) + (x + 5) = 2x + 9
2x (1+3)=(2x1+(2x3)
x = 15
5+x=x+5 is an example of the commutative property of addition.

If its x+4x+5 then: 5x+5
x+4x+5=5x+5
x - 8 + x - 5 + x + 1 = 3x - 12
Yes it does
