Answer: b+5a</h3>
Explanation:
The commutative property of addition is where we can add two numbers in any order.
The general equation is x+y = y+x
A more concrete example would be something like 2+3 = 3+2 since both sides simplify to 5.
For 5a+b, it is the same as b+5a. We swap the two terms.
Answer:
994
Step-by-step explanation:
PEMDAS
Parentheses: 8+2 = 10
Exponents: 10^3 = 1000
Subtraction = 1000-6
= 994
