Answer:
Step-by-step explanation:
Factor the expression. Factoring is the process of writing out an expression by using other expressions such that when the other expression are multiplied together, the resulting expression is the initial expression.
Now set the expression equal to zero to find the roots (also known are zeros) of the expression. Use the zero product property to find the answers, the zero product property states that any number times zero is zero.

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 that answers your question ;)
The probability that all three of the selected vials have hairline cracks = 0.096
Total number of vials in the shipment = 62
Number of vials with hairline cracks = 14
Number of vials without hairline cracks = 48
Three from 62 vials are selected.
So total outcomes = 62C3
Number of possible outcomes for all 3 of selected vials have hairline cracks = 14C3, which is the number of favorable outcomes
Probability that all three of the selected vials have hairline cracks = Number of favorable outcomes/Total outcomes = 14C3/62C3 = 0.096

Answer:
79
Step-by-step explanation:
Let the original number be x.
x/2 = 39.5
x = 39.5 × 2
x = 79
