The square root of five is 2.2.
4 x 2.2 = 8.8
Hope I could help!
Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.
![x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%2B%2F-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
For us, it looks like this:
![x=\frac{-3+/-\sqrt{(-3)^2-4(5)(4)} }{2(5)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%2B%2F-%5Csqrt%7B%28-3%29%5E2-4%285%29%284%29%7D%20%7D%7B2%285%29%7D)
which simplifies to
![x=\frac{-3+/-\sqrt{-71} }{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%2B%2F-%5Csqrt%7B-71%7D%20%7D%7B10%7D)
Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that ![i^2=-1](https://tex.z-dn.net/?f=i%5E2%3D-1)
so we will do a rewrite on that equation above:
![x=\frac{-3+/-\sqrt{i^2*71} }{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%2B%2F-%5Csqrt%7Bi%5E2%2A71%7D%20%7D%7B10%7D)
which simplifies further to
![x=\frac{-3+/-i\sqrt{71} }{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%2B%2F-i%5Csqrt%7B71%7D%20%7D%7B10%7D)
This is the answer but we can separate it into its proper standard form which is
and ![x=-\frac{3}{10}-\frac{\sqrt{71} }{10}i](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B3%7D%7B10%7D-%5Cfrac%7B%5Csqrt%7B71%7D%20%7D%7B10%7Di)
6 multiplied by 4 is 24 feet. Then convert it to meters by multiplying .3048 by 24 which means the answer is 7.3152 meters
Answer:
54°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so;
![9x+9=8x+14 \\ \\ x=5 \\ \\ m\angle S=9(5)+9=54^{\circ}](https://tex.z-dn.net/?f=9x%2B9%3D8x%2B14%20%5C%5C%20%5C%5C%20x%3D5%20%5C%5C%20%5C%5C%20m%5Cangle%20S%3D9%285%29%2B9%3D54%5E%7B%5Ccirc%7D)
