Answer:False
Step-by-step explanation:
5^2+13^2=14^2
25 +169=196
194 ≠ 196
They’re not equal meaning it’s not a right triangle. Sorry for my first answer. I was supposed to use the Pythagorean theorm
Answer:
-8, 0
Step-by-step explanation:
The floor and ceiling functions have equal values for any integer argument. Their value is that integer.
Among your answer choices, the integers are -8 and 0.
60% of 10 is 6, so 10x6 is the area which is 60ft^2
Answer:
60
Step-by-step explanation:
180-120= 60
a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.

If we can write a polynomial in the form
, then we can factor it as:
![a^2-b^2=(a-b)(a+b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29)
In this problem, we have the following expressions:
![1. \ y^5 - 25 \\ \\ 2. \ 9m^2n^2-121 \\ \\ 3. p^{18} - q^{10} \\ \\ 4. 16r^2 - 27](https://tex.z-dn.net/?f=1.%20%5C%20y%5E5%20-%2025%20%5C%5C%20%5C%5C%20%202.%20%5C%209m%5E2n%5E2-121%20%20%5C%5C%20%5C%5C%203.%20p%5E%7B18%7D%20-%20q%5E%7B10%7D%20%5C%5C%20%5C%5C%204.%2016r%5E2%20-%2027)
- For 1 and 4 we can't write this in the form
so this is not a difference of squares.
![9m^2n^2-121 =3^2m^2n^2-11^2 \\ \\ =(3mn)^2-11^2 =(3mn-11)(3mn+11)](https://tex.z-dn.net/?f=9m%5E2n%5E2-121%20%3D3%5E2m%5E2n%5E2-11%5E2%20%5C%5C%20%5C%5C%20%3D%283mn%29%5E2-11%5E2%20%3D%283mn-11%29%283mn%2B11%29)
So we could write 2 as a difference of squares.
![p^{18} - q^{10}=(p^9)^2-(q^5)^2=(p^9-q^5)(p^9+q^5) \\ \\ \\ Remember: \ (a^m)^n=a^{mn}](https://tex.z-dn.net/?f=p%5E%7B18%7D%20-%20q%5E%7B10%7D%3D%28p%5E9%29%5E2-%28q%5E5%29%5E2%3D%28p%5E9-q%5E5%29%28p%5E9%2Bq%5E5%29%20%5C%5C%20%5C%5C%20%5C%5C%20Remember%3A%20%5C%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D)
So we could write 2 as a difference of squares.
