Answer:
1. The correct answer is B. <em>N</em>
3. The answer is C.) Associative Property of Addition
Step-by-step explanation:
1. Since , then it means that -4 cannot be a natural number (<em>N</em>). By definition, natural numbers ( <em>N </em>) are counting numbers that are positive integers.
3. According to the Associative Property of Addition:
(<em>a</em> + <em>b</em> ) + <em>c</em> = <em>a </em>+ (<em>b </em>+ <em>c </em>)
This definition matches your test question, "(7<em>a</em> * 2b) + 3c = 3c + (7<em>a</em> * 2b)"
Hope this explanation helps :)
Henrietta solved a rational equation by multiplying both sides by .She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right
