Answer:
the number of ways to form a 5 digit pin using the given digits is 720
Step-by-step explanation:
You can simplify a factor 2 in the first fraction:
![\dfrac{2e}{2n} = \dfrac{e}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7B2e%7D%7B2n%7D%20%3D%20%5Cdfrac%7Be%7D%7Bn%7D)
And you can ignore the ones in the second:
![\dfrac{1w}{1n} = \dfrac{w}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7B1w%7D%7B1n%7D%20%3D%20%5Cdfrac%7Bw%7D%7Bn%7D)
If two fractions have the same denominator, you can sum the numerators:
![\dfrac{e}{n}+\dfrac{w}{n} = \dfrac{e+w}{n}](https://tex.z-dn.net/?f=%5Cdfrac%7Be%7D%7Bn%7D%2B%5Cdfrac%7Bw%7D%7Bn%7D%20%3D%20%5Cdfrac%7Be%2Bw%7D%7Bn%7D)
Answer:
Finding the bottom area:
12 + 2 = 14 x 2 = 28
Triangle Area: 4 + 2 = 6 x 4 = 24 divided by 2 is 12
Top left figure area is:
2 x 8 = 16
Add all of it together: 28 + 12 + 16 = 56

Logical answer
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°
