First, try multiplying multiple numbers to see if you get these numbers.
2=4,6,8,10,12,14,16,18,20,22,24,26,(28),30,32,34,36,38,40,(42)
7=7,14,21,(28),35,(42)
14= 14,(28),(42)
14, would be best; Alternatively, the GCF of 28 and 42 can be found using the prime factorization of 28 and 42.
<span>-The factors of 28 are 28, 14, 7, 4, 2, 1.<span>
-The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1.
Common numbers: 1 , 2, 7,14 , the largest number that can go into both is 14.

First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:
4(x + 2) = 5(x + 6)
Now, you need to get rid of the parenthesis by distributing:
4x + 8 = 5x + 30
Subtract both sides by 5x:
-x + 8 = 30
Subtract both sides by 8:
-x = 22
Now, divide both sides by -1:
x = -22
P.S.: You don't really need a calculator to solve.
Answer:
49 different ways
Step-by-step explanation:
If there are seven roads that lead to the top, you have seven possible choices to go to the top of the hill.
Then, to come back to the start, you also have seven possible choices (seven roads), and you can pick any road.
So, if you have seven ways go to up and seven ways to go down, the number of different ways of going to the top and come back is the product these numbers of possible choices.
N(total) = N(up) * N(down)
N(total) = 7 * 7
N(total) = 49 different ways
