Answer:
y = 2x + 2
Hope you have a great day!
diagonals ( n is the number of sides )
Solve;
If each cm = 4 meters, then you multiply.
4*2
= 8
There are 2 cm, each cm = 4 meters, so you multiply to get your answer.
The final height of the door is 8 meters.
Answer:
![-5-\sqrt{-44}=-5-2\sqrt{11}i](https://tex.z-dn.net/?f=-5-%5Csqrt%7B-44%7D%3D-5-2%5Csqrt%7B11%7Di)
Step-by-step explanation:
We want to simplify:
![-5-\sqrt{-44}](https://tex.z-dn.net/?f=-5-%5Csqrt%7B-44%7D)
We rewrite the expression under the radical sign to obtain:
![-5-\sqrt{4\times11\times -1}](https://tex.z-dn.net/?f=-5-%5Csqrt%7B4%5Ctimes11%5Ctimes%20-1%7D)
We split the expression under the radical sign to get:
![-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}](https://tex.z-dn.net/?f=-5-%5Csqrt%7B4%7D%20%5Ctimes%20%5Csqrt%7B11%7D%20%5Ctimes%20%5Csqrt%7B-1%7D)
Recall that:
![\sqrt{-1}=i](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D%3Di)
This implies that:
![-5-\sqrt{4} \times \sqrt{11} \times \sqrt{-1}=-5-2\sqrt{11}i](https://tex.z-dn.net/?f=-5-%5Csqrt%7B4%7D%20%5Ctimes%20%5Csqrt%7B11%7D%20%5Ctimes%20%5Csqrt%7B-1%7D%3D-5-2%5Csqrt%7B11%7Di)
Therefore ![-5-\sqrt{-44}=-5-2\sqrt{11}i](https://tex.z-dn.net/?f=-5-%5Csqrt%7B-44%7D%3D-5-2%5Csqrt%7B11%7Di)
