Answer:
b
Step-by-step explanation:
Answer: x=5 and x=-1
Step-by-step explanation:
X^2-4x-5=0
(X-5) (x+1)=0
X-5=0. And. X+1=0
The answers 15 because we have two negatives it's always a positive and 3×5 is 15
For example, for LCM (12,30) we find:
Using the set of prime numbers from each set with the highest exponent value we take 22 * 31 * 51 = 60. Therefore LCM (12,30) = 60.
