Answer:
x >1/5
Step-by-step explanation:
5x-1 >0
Add 1 to each side
5x-1+1 >0+1
5x >1
Divide each side by x
5x/5 >1/5
x >1/5
a²+b² = c² where a and b are legs and c is the hypotenuse
So...
a²+4²=13²
a²+16=169
a²=153
a=√153
answer: approx. 12.37 units
Hey there! :D
Since all the terms are being added together, and there is a common denominator with the fractions, we can just add them.
x+x= 2x 3/4+2/4= 5/4
2x+5/4
2x+1.25<== simplest form
I hope this helps!

I will get you started.
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
You must now use the quadratic formula.
In the formula, a = 1, b = 4, and c = -12.
Take it from here.
