Assuming you know the quadratic formula:
You can fill in a, b and c in this and get:
Now, let's create a shorthand 
to make the writing easier:
But since one root is three times the other root (but we don't know which one), we also know that:
or 
If you solve this, you get:
or 
However, since q is a square root, it must be postive.
So we know that:
From this you find that
So p = 3/2
The roots are x=1/2 and x=3/2.

Hey there!
First, let's look at what perpendicular means. Imagine a cross, where there's all 90 degree angles. That's exactly what we're talking about when we say perpendicular. The given equation is in slope-intercept form, where we have:
y = mx + b
where m is the slope and b is the y-intercept.
When we're writing an equation with a perpendicular slope, we use the negative reciprocal of the given slope. Thus, we can make 0.3 1/3, and take the reciprocal to make 3, and make it negative 3 as it's the negative reciprocal. Now, we know we have a line with the slope of -3 and goes through (-3, 8). We can use the x and y values in this set of points, along with the slope, to create an equation to solve for b. That gives us:
8 = -3(-3) + b
8 = -9 + b
17 = b
Now, since we have slope and y-intercept, we can write our equation as:
y = -3x + 17
Hope this helps!

Answer:
Step-by-step explanation:
Given:
The 
term of the sequence is given as:
In order to find the fourth term of this sequence, we need to plug in 4 for 
in the above expression and solve. This gives,
Therefore, the fourth term of the sequence is .
