900 because 9 is greater than 5 so it rounds to my answer.
Step-by-step explanation:
8.
Prime factorization of 48 is :

Option (3) is true.
9.
Prime factorization of 19 is:
19 = 19 × 1
Option (c) is correct.
(10).
Prime factorization of 924 is:
924 = 2 x 2 x 3 x 7 x 11
= 2² x 3¹ x 7¹ x 11¹
Hence, this is the required solution.
Sqrt55. Use the pythagorean theorem; 3^2 + x^2 = 8^2
I’m pretty sure it should be ,B
