we have
![x^{2}+2x + 1 > 0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B2x%20%2B%201%20%3E%200)
we know that
![x^{2}+2x+1=(x+1)^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B2x%2B1%3D%28x%2B1%29%5E%7B2%7D)
so
![(x+1)^{2}> 0](https://tex.z-dn.net/?f=%28x%2B1%29%5E%7B2%7D%3E%200)
two solutions
<u>first solution </u>
![(x+1)> 0](https://tex.z-dn.net/?f=%28x%2B1%29%3E%200)
![x > -1](https://tex.z-dn.net/?f=x%20%3E%20-1)
the first solution is the interval---------> (-1,∞)
<u>second solution</u>
![-(x+1)> 0](https://tex.z-dn.net/?f=-%28x%2B1%29%3E%200)
![-x-1> 0](https://tex.z-dn.net/?f=-x-1%3E%200)
![-x> 1](https://tex.z-dn.net/?f=-x%3E%201)
![x< -1](https://tex.z-dn.net/?f=x%3C%20-1)
the second solution is the interval---------> (-∞,-1)
therefore
the solution is all real numbers except the number ![-1](https://tex.z-dn.net/?f=-1)

Answer:
15x+5
Step-by-step explanation:
First you distribute the 5 to the 3x ( 5 times 3x=15x)
Next you distribute the 5 to the 1 (5 times 1=5)
Finally you put the two answers together 15x+1
you cant simplify it anymore because you cannot add 15x to 1
1.c 2. b 3. b 4.a 5.b 6.c these are the correct answers
Since both trains in total weigh 360 tons and train A weighs more than train be, it means that train B is the rest of the weight when you subtract train A from the total amount. Difference means subtraction so just solve this: 360-272 to get train B and you already know that train A is 272 tons. Please mark branliest!
To find the area of a parallelogram, multiply the base by the height. the formula is: A= Base times height where B is the base, and H is the height, and * means multiply. the base and height of a parallelogram must be perpendicular
