Answer:

Step-by-step explanation:
Hi!
This is a lot of radicals, so it may seem tricky. Let's begin by simplifying all of the radicals that can be simplified.
We can see that
can be simplified.
Taking prime factorization:

which is:

So an updated equation is
.
Now, we need to expand this:
First, let's expand the parenthesis:
.
We can apply some of are rules:

And, now to simplifying!
Adding similar elements:

Simplifying and cleaning up each radical:
.
Now all we have to do is add the similar elements (again.)
In doing so we reach an answer of 
Hope this helps!

5x² + 25x = 0
5x(x) + 5x(5) = 0
5x(x + 5) = 0
5 5
x(x + 5) = 0
x = 0 or x + 5 = 0
- 5 - 5
x = -5
The surface area of a square is determined by multiplying the length and width by each other, for example:
If a square is 10 units high and 5 units long, then the surface area would be 50 units.
Answer:
y = 4/5x -1
Step-by-step explanation:
The slope-intercept form of the equation of a line is ...
... y = mx + b . . . . . . for slope m and y-intercept b
You have m = 4/5 and b = -1. The equation of the line is found by putting these values in their places in the form above.
... y = 4/5x -1
