The next number would be 19.
Each number adds one more each time.
For example, 4+0=4, 4+1=5, 5+2=7, 7+3=10, 10+4=14, 14+5=19
Hopefully this makes sense, its kind of hard to explain.
Hope this helps :)
Answer:

Step-by-step explanation:
A right angled ∆ is given to us and we need to find out the value of cos 45° ( with rationalized denominator ) . As we know that in a right angle ∆ , the value of cosine is ,
In the given triangle ,
- Value of base = 1
- Value of hypotenuse = √2
On substituting the respective values ,
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
Simplify ,
The value of b to 2.
By doing that you are applying a vertical translation to the function
If you divide 8 from 140 you'll get 17.5 or 1120<span />
7×65 7×(60+5)
(7×60) (7×5)
(420)+(35)
The answer is 455
