- The expression was rewritten using the commutative law of addition.
- Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots.
- Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.
<h3>What is the
commutative law of addition?</h3>
The commutative law of addition is also referred to as the law of cumulative addition and it states that if two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.
This ultimately implies that, the sum of addends would always be the same (equal) regardless of their arrangement in accordance with the commutative law of addition. Mathematically, the commutative law of addition can be represented using the following formula:
A + B = B + A.
In this context, we can reasonably infer and logically deduce that the given expression was rewritten using the commutative law of addition.
In conclusion, Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

Answer:
The answer is x=-1
B) {x|x ∈ U and 2x is prime}
x is greater than 1.
the only even prime number is 2
2 times anything is even.
the minimum x value is 2. 2x is 4, therefore higher than the only even number
every value 2x will have a multiple of 2 so it will not be prime.
