PLEASE HELP! Lina and Josh each made a factor tree to find the prime factorization of 126.

Answer 1

Its A if they are talking about a prime factorization tree.<span />

Answer 2

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 $3 \times 3$  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.
