No because the sum could also be irrational number which for example it could be square root of 9 or 49

Answer:
Vertex is at (4, 2)
Step-by-step explanation:
to find the 'x' value of the vertex, use 'x = -b/2a'
in this problem, a = 1, b = -8, c = 18
x = -(-8)/2(1)
x = 8/2
x = 4
plug 2 in for 'x' in equation and solve for 'y':
y = 4² - 8(4) + 18
y = 16 - 32 + 18
y = -16 + 18
y = 2
Vertex is at (4, 2)

The property of a(b+(-b))=(b+(-b))a is called as Commutative Property of Multiplication.
The Commutative Property in mathematics is a rule that allows interchange the order of terms or factors without any change in the end result.
In multiplication, we can interchange the factors without affecting the end result of multiplication. For example, 2 x 3 = 3 x 2 = 6
In addition, we can interchange the terms without affecting the summation result. For example, 2+3 = 3+2 = 5
But Commutative Property does not apply to subtraction or division.
For example, 2-3 != 3-2
or, 2/3 != 3/2
Hence the answer to the question is Commutative Property of Multiplication.
