Answer:
x=8 & x=6
Step-by-step explanation:
Answer:
the inequality woulds be *less than
Step-by-step explanation:
To determine what the value of X is simply use the appropriate trigonometric ratio, which in this case is cos.
Cos 21 = 3/X
X • cos 21 = 3
X = 3/(cos 21)
X = 3.123 about 3.1
The value of X to the nearest tenth would be about 3.1.
Start with
Multiply both sides by 9:
Divide both sides by 5:
Add 32 to both sides:
The lack of parenthesis makes it hard for me to understand what you mean with aC+b/c, since it could be both

Hello!
The discriminant of a quadratic function is found by using this formula:
D = b² - 4ac
Once you substitute the values into the formula, there are three ways your answer can be interpreted.
1. If the discriminant is positive, then there are two rational solutions.
2. If the discriminant is negative, then there are no rational solutions.
3. If the discriminant is equal to zero, then there is only one rational solution.
Given the equation, 2x² + 14x + 11 = 0, a = 2, b = 14, and c = 11.
14² - 4(2)(11)
196 - 88 = 108
Since the discriminant, 108, is a positive integer, the answer is C, there are two rational solutions.
