Answer:
I do not think I can answer this without any pictures.
Step-by-step explanation:
Sorry, but could you attach a link or maybe sketch it out?
If you mean 5^2 and not 5^2i then
5^2 just means 5 times itself,twice or 5 times 5 or 25
if you meant 5^2i
i=√-1
so law of exponents says a^(xz)=(a^x)^z so
5^2i=(5^2)^i or (25)^i
the answer (if you wanted 5^2i) is 25^i
IF YOU MEANT 5^2 then the answer is 25
Answer:

Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces
so
![SA=b^2+4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3Db%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have

substitute
![SA=1^2+4[\frac{1}{2}(1)(2)]](https://tex.z-dn.net/?f=SA%3D1%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%281%29%282%29%5D)

Answer:
This system of equations has <em>no solution</em>. It is inconsistent.
Step-by-step explanation:
The last equation tells you z = -1.
Substituting this value for z in the other two equations allows them to be written as ...
-3x -y = 7
-3x -y = 3
There are no values of x and y that can make both these equations true.
