Answer:
8:30 pm
Step-by-step explanation:
step 1
Decompose the numbers in prime factors
step 2
Find the LCM
The LCM of 30 min and 35 minutes will be given as
step 3
Adds 210 minutes to the starting time
First, converting 210 minutes to hours
Remember that
will need dividing 210 by 60
therefore
5:00 pm+3.5 h=8:30 pm
Answer:
x=-5, 7 are the excluded values
Step-by-step explanation:
Excluded values are the values that makes the denominator 0
To find excluded values we set the denominator =0 and solve for x
Factor x^2 - 2x - 35
(x-7)(x+5) =0
We set each factor =0 and solve for x
x-7 =0 so x= 7
x+5 =0 so x= -5
x=7, x=-5 makes the denominator 0
So x=7 , x=-5 are the excluded values
Answer:
