ANSWER
I. The GCF of 6 and 16 is 3. FALSE
II. The LCM of 6 and 16 is 48. TRUE
III. 6 and 16 are both composite numbers. TRUE.
EXPLANATION
The GCF of 6 and 16 is not 3.
It is rather 2.
Factors of 6: {1,2,3,6}
Factors of 16:{1,2,4,8,16}
3 is not even a factor of 16.
The LCM of 6 and 16 is 48. This statement is true.
Composite numbers have more than 2 factors.
6 and 16 are both composite numbers.
Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
= 
Note that AD = 33 - 22 = 11
Substitute values into the ratio
= 
= 
( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
= 
, substitute values
= 
= 
( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A
