I used the <span>quadratic formula to solve this problem. if you have anymore questions or cant reading my writing clearly, please message me :)

So you've gotta have a variable representing the number of seconds between the time when you see lightning and the time when you hear thunder. I'm going to use <em>x.
</em>So equation:
<em /><em>x</em>/5=2
Solving:
you have to multiply both sides by five, so it becomes:
<em>x</em> = 10
so it's 10 seconds!
The interest is simple
A=5,200×(1+0.04×5)
A=6,240
Answer:
8
Step-by-step explanation:
When we look at sequences, we have the function and we have the sequence, the sequence is f(x)... f(n)... or just f with any variable within a parenthesis right next to it.
What the variable signifies is the value that we will be replaced within the sequence, which is 2n in this case. So by your question, it we are looking for the fourth term, that means f(4) = 2n. Since n is replaced with 4, we do the same with the sequence.
2(4)
Multiply
