The answer is 81 because if we plug in 9:
9^2 * 9^0
We know that anything to the zero power is one, so we are left with
9^2 which equals 81

Look below for answer! Have a great day and please mark me brainliest!
Step-by-step explanation:
Bedroom 1: 22x15=330
330x7.25=2392.5
Bedroom 2: 15x12=180
180x7.25=1305
Bedroom 3: 13x12=156
156x7.25=1131
2392.5+1305+1131= 4828.5
Bedroom 1: 22x15=330
330x6.75=2227.5
Bedroom 2: 15x12=180
180x6.75=1215
Bedroom 3: 13x12=156
156x6.75=1053
2227.5+1215+1053+100= 4595.5
Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.
The answer would be 2√5/5
As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.
Hopefully, my explanation makes sense. :)

Answer:
The equation of plane is

Step-by-step explanation:
We have to find the equation of plane passing through the point (0,-1,1) and orthogonal to the planes

Thus, we can write:

We will evaluate:
![n = n_1\times n_2\\\\n = \left[\begin{array}{ccc}i&j&k\\3&4&-3\\-3&2&4\end{array}\right] \\\\n = i(16 + 6)-j(12-9) +k(6+12)\\n = 22i-3j+18k\\n =](https://tex.z-dn.net/?f=n%20%3D%20n_1%5Ctimes%20n_2%5C%5C%5C%5Cn%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Di%26j%26k%5C%5C3%264%26-3%5C%5C-3%262%264%5Cend%7Barray%7D%5Cright%5D%20%5C%5C%5C%5Cn%20%3D%20i%2816%20%2B%206%29-j%2812-9%29%20%2Bk%286%2B12%29%5C%5Cn%20%3D%2022i-3j%2B18k%5C%5Cn%20%3D%20%3C22%2C-3%2C18%3E)
The required plane passes through the point (0,-1,1)
Thus, the equation of plane is

is the required equation of the plane.
