Answer:
16
Step-by-step explanation:
f(x) = 2x + 4
f(6) = 2(6) + 4
=> f(6) = 12 + 4
=> f(6) = 16
Answer:
86400
Step-by-step explanation:
There are 10 seats. If the Scooby Doo gang will seat adjacent, then we can assume them to be 1 group. This means we are to evaluate the number of ways of seating 6 people. This is given by .
But the Scooby Doo gang of 5 can seat within themselves in ways.
Total number of possible arrangements .

<span>Which expression can be used to determine the side length of the rhombus?
The answer is the first option: 10/Cos(30°) Explanation:
1. As you can see in the figure attached, there is a right triangle and its hypotenuse (which is represented with the letter "x") is the side you want to calculate. So, you have:
Cos(</span>α)=Adjacent leg/Hypotenuse
<span>
</span>α=30°
<span> Adjacent leg=(20 in)/2=10 in
Hypotenuse=x
2. When you substitute these values into the formula, you obtain:
</span>
Cos(α)=Adjacent leg/Hypotenuse
<span> Cos(30°)=10/x
3. Therefore, you obtain the expression to determine the side length of the rhombus by clearing the hypotenuse "x", as below:
x=10/Cos(30°)

I think it would be y/2y+3
