X² + 11x - 26 = 0
x² - 25 = 0

(x + 13)(x - 2) = 0
(x + 5)(x - 5) = 0

x = -13
x = 2
x = -5
x = 5

Hello!

Judging on the questions you have provided I have come to the conclusion that to solve all of these you need to find the value of x by isolating it all on one side and simplifying.

For question #1 the first step would be to subtract 6 from each side.
The outcome should be -x=-6-12, and if simplified -x=-18.
Next, you want to divide each side by -1 because x needs to always be positive when finding the solution.
Your answer for #1 should be X=18, D.

For question #2 the first step you should take is to subtract 1.33 from each side to isolate x. 
The outcome should be x=7.82-1.33, and if simplified x=6.49.
Thus your answer for #2 should be X=6.49, A.

For question #3 the first step you should take to approaching the equation is to isolate x by adding 15.99 towards each side of the equation.
The outcome should be x=58.06+15.99, and if simplified x=74.05.
Thus your answer for question #3 should be X=74.05, D.

Lastly, for question #4 the first step you should take towards isolating x is to divide the entire equation by 1.32.
Your outcome should be x= 6.8
Thus, your answer for the last question, #4, should be X=6.8, C.

Hope this helped!

The answer is 3/5.


\frac{1}{3} *\frac{3}{5} =\frac{3}{15} \\ \\ \frac{3}{15} *\frac{3}{5} =\frac{9}{75}


Continue this pattern and you'll see that it follows this geometric sequence
