The commutative property says that a+b=b+a. Basically the sum is the same no matter the order in which you add the terms.
Final answer: 9+3=12

Hello from MrBillDoesMath!
Answer:
Take you pick below! (either x 8 or x = 7.01, approx, depending how the question is interpreted)
Discussion:
Interpretation 1
If the question is
2^(x -1) = 128, then as 2^7 = 128,
x-1 = 7 so x = 8
Interpretation 2
If the question is (2^x -1) = 128, then..
2^x = 128 + 1 = 129 =>
log(2^x) = log(129) =>
xlog(2) = log(129) =>
x = log (129) / log2 = 7.01

Answer:
-6/7
Step-by-step explanation:
x2+5x+6=0
7x+6= 0
-6 -6
7x= -6
/7 /7
x= -6/7 or -0.85714285714
The correct answer is D) it has two factors and the factor (5+y) has 2 terms.
The factors are what are multiplied to make the expression. In this expression, (5+y) and 8 are multiplied, so those are the 2 factors.
The factor (5+y) has two terms, 5 and y.
