Your answer is A have a good day
Answer:
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Step-by-step explanation:
![3x + 11 = 26](https://tex.z-dn.net/?f=3x%20%2B%2011%20%3D%2026)
![3x = 15](https://tex.z-dn.net/?f=3x%20%3D%2015)
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
P=2(l + b)
P=2l + 2b
P-2b=2l
P-2b/2=l
C is your answer
Answer:
D. ![A\subset \mathbb{R}\times\mathbb{R}.](https://tex.z-dn.net/?f=A%5Csubset%20%5Cmathbb%7BR%7D%5Ctimes%5Cmathbb%7BR%7D.)
Step-by-step explanation:
Consider the set
![A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}](https://tex.z-dn.net/?f=A%3D%5Cleft%5C%7B%282%2C3%29%2C%5C%20%285%2C1%29%2C%5C%20%28-3%2C-2%29%2C%5C%20%280%2C3%29%5Cright%5C%7D)
This set consists of four ordered pairs.
The first numbers in these pairs are
These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are
These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and
![A\subset \mathbb{R}\times\mathbb{R}.](https://tex.z-dn.net/?f=A%5Csubset%20%5Cmathbb%7BR%7D%5Ctimes%5Cmathbb%7BR%7D.)
