Hey!
-----------------------------------------------------------
Solution:
= 7√3 + 2√9
= 7√3 + 6
= 18.124... (Non-Terminating or Irrational)
When we add a rational number and a irrational number it's always irrational.
-----------------------------------------------------------
Answer:
The answer 7√3 + 6 is irrational because the sum of a rational number and irrational number is an irrational number.

Hope This Helped! Good Luck!
I think the answer will be 9.5x
Answer:
B and D
Step-by-step explanation:
To determine which point is a solution, substitute the x- coordinate into the right side of the equation and if the value obtained agrees with the y- coordinate then it is a solution.
(5, 10)
y = 5² - 2(5) + 1 = 25 - 10 + 1 = 16 ≠ 10 ← not a solution
(- 1, 3)
y = (- 1)² - 2(- 1) + 1 = 1 + 2 + 1 = 3 ← This is a solution
(1, 2)
y = 1² - 2(1) + 1 = 1 - 2 + 1 = 0 ≠ 2 ← not a solution
(3, 4)
y = 3² - 2(3) + 1 = 9 - 6 + 1 = 4 ← this is a solution
Answer: 30
Step-by-step explanation:5(Z+4) + 5(2-Z).
Open the brackets by multiplying true by the number out of the bracket.
5Z + 20 + 10 - 5Z
Now, collect like terms, we have.
5Z - 5Z + 20 + 10. Now we have
0 + 30 = 30//
