1yard =3ft so 》 6ft/4×3ft=6/12=1/2
You have to go past the decimal point in since the first number in the tenths place is a zero you can't really round here so you go to the hundreds place and not so three you round down because 3 is closer to 0 then it is 10 so it would be 1. 4
5p+7c=2p
5p=2p-7c
7p=-7c
p=-c
hope it helped

Step-by-step explanation:
1) √4 . √-3 . √-3
![$ \sqrt{4} = 2 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B4%7D%20%3D%202%20%24)
![$ \sqrt{-3} . \sqrt{-3} = (\sqrt{-3})^2 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B-3%7D%20.%20%5Csqrt%7B-3%7D%20%3D%20%28%5Csqrt%7B-3%7D%29%5E2%20%24)
-6
2) √-4 . √-3 . √-3
.
Therefore,
- 6i
3) √4 . √3 . √-3
![$ \sqrt{4} = 2 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B4%7D%20%3D%202%20%24)
![$ \sqrt{3} . \sqrt{-3} = (\sqrt{3})^2 . \sqrt{-1} $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B3%7D%20.%20%5Csqrt%7B-3%7D%20%3D%20%28%5Csqrt%7B3%7D%29%5E2%20.%20%5Csqrt%7B-1%7D%20%24)
6i
4) √4 . √3 . √3
![$ \sqrt{4} = 2 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B4%7D%20%3D%202%20%24)
![$ \sqrt{3} . \sqrt{3} = (\sqrt{3})^2 = 3 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B3%7D%20.%20%5Csqrt%7B3%7D%20%3D%20%28%5Csqrt%7B3%7D%29%5E2%20%20%3D%203%20%24)
Therefore, √4 . √3 . √3 = 2 . 3 = 6
