PLEASE HELP! Lina and Josh each made a factor tree to find the prime factorization of 126.
2 answers:
Answer:
Lina’s solution is correct because it expresses 126 as a product of prime factors.
Step-by-step explanation:
Given :
Lina Josh
126 126
/ \ / \
3 42 2 63
/ \ / \
6 7 9 7
/ \
2 3
Solution:
Since Josh didn't solved it further as 9 can be written as further.
So, Josh's solution is incorrect.
Hence option A is correct.
Lina’s solution is correct because it expresses 126 as a product of prime factors.

Answer:
c (all real numbers)
Step-by-step explanation:
The first inequality has the solution ...
3 + v ≤ -4
v ≤ -7 . . . . . . . subtract 3 from both sides
__
The second inequality has the solution ...
-2v ≤ 14
v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality
__
So, the solution to the compound ...
v ≤ -7 or -7 ≤ v
is every number — <em>all real numbers</em>. The graph of that is the entire number line, as in choice C.
