Answer:
![\frac{40}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B4%7D%20)
Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:
![\frac{40 tiles}{4} = 10 groups](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%20tiles%7D%7B4%7D%20%3D%2010%20groups%20)
Therefore, the expression modeled by the arrangement of the tiles is ![\frac{40}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B4%7D%20)
Answer:
1)=0
2)
![\frac{ \sqrt{3} }{?2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%7B3%7D%20%7D%7B%3F2%7D%20)
3)
![\sqrt{3}](https://tex.z-dn.net/?f=%20%5Csqrt%7B3%7D%20)
4)
![2 + \sqrt{3}](https://tex.z-dn.net/?f=2%20%2B%20%20%5Csqrt%7B3%7D%20)
5) I don't know that one.
Hello :
Φ + <span>3π/7 = </span>π
Φ = π - 3π/7
Φ =4π/7
Answer:
420
Step-by-step explanation:
7 * 3 = 21
21 * 2 = 42
42 * 10 = 420
7 * 3 * 2 * 10 = 420
<u>The area is 420</u>
