Answer:
x = - 7, x = 0
Step-by-step explanation:
Given
x² + 7x = 0 ← factor out x from each term on the left side
x(x + 7) = 0
Equate each factor to zero and solve for x
x = 0
x + 7 = 0 ⇒ x = - 7

Answer:
1/3 part of 120 hours....
Answer:
I would rather use their multiples.
Step-by-step explanation:
With 13 and 14, neither number has many factors (and few prime factors, for that matter) so factoring would be pretty much useless. If you wanted to use the prime factors of 14 (7 and 2) multiplying either of them by 13 would not give you the LCM. Actually the LCM is just 13*14 which is 182.
Good luck!
Answer:
-18, 30
Step-by-step explanation:
