Step-by-step explanation:
This is a simple proportion problems.
7 kilogram weight attache to a spring stretches = 6 meters
1 kilogram would stretch = 6/7 m

= 36 meters.
UGH I think I did this before but I totally forgot how to do it. Give me a minute to do some research and remember because I'm about 79% sure I know how to do this!
Answer:
3(3a - 6b + 7c )
Step-by-step explanation:
The greatest common factor of 9, 18 and 21 is 3
Factor out 3 from each term
9a - 18b + 21c
= 3(3a - 6b + 7c) ← in factored form
Answer:
Um wat?
Step-by-step explanation:
Answer:
n = 2 or n = 3/2 thus A. is the Answer
Step-by-step explanation:
Solve for n:
2 n^2 - 7 n + 6 = 0
The left hand side factors into a product with two terms:
(n - 2) (2 n - 3) = 0
Split into two equations:
n - 2 = 0 or 2 n - 3 = 0
Add 2 to both sides:
n = 2 or 2 n - 3 = 0
Add 3 to both sides:
n = 2 or 2 n = 3
Divide both sides by 2:
Answer: n = 2 or n = 3/2
