The expressions in the figure below represent the measures of two angles. Find the value of x. f||g.

Nadusha1986 [10]

So before we find the value of x, let us remember that the sum of two angles is 180 degrees. Now, let us solve for x.
180 = 7x + 2x + 36
180 = 9x + 36
180-36 = 9x
144 = 9x <<divide both sides by 9
and the result would be 16.
Therefore x =16.
I hope this is the answer that you are looking for. Let me know if you need more help next time.

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

Answer:

There are no simple factors to this expression. You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:

$y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}$
