Answer:
A) 2(9x - 2)
Step-by-step explanation:
The greatest common factor of 18x and -4 is 2.
B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.
C is wrong because 18x cannot be divided by 4 to produce a whole number.
D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.
Answer:
<h2>(A) 9</h2>
Step-by-step explanation:
Let’s put the number of the set 6, 10, 2, 7, 13, 15 in order from least to greatest :
2 , 6 , 7 , 10 , 13 , 15
we know that the median is the central value of the number set
then
if the median is 10
then x should be placed between 10 and 13 or 13 and 15
which means
x ≥ 10
therefore
9 could NOT be the value of x
