Step-by-step explanation:
If you can't factor the polynomial then you won't be able to even start the problem or even end it
A little Algebra, and we're home free!
We are given R = 20 and r2 = 75. We need to find r1.
The formula is 1/R = 1/r1 + 1/r2. Plug-in:
1/20 = 1/r1 + 1/75
1/20 - 1/75 = 1/r1
0.0366 = 1/r1
r1 = 1/0.03666
r1 = 27.272
Our answer is r1 = 27 ohms.
Answer: 250 miles
Step-by-step explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x <u> 1 hour </u> x<u> 100 miles </u>= 250 miles
60 mins. 1 hour
(x+4)(x+6)=0
x = -4, x=-6
The answer is C.
