Answer:
9x - 45
Step-by-step explanation:
To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.
-9(-x + 5)
-9 · -x = 9x
-9 · 5 = -45
Now we add our products together.
9x + -45
Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.
9x - 45

In typeset formulas, radicals, fraction bars, and superscript formatting serve to group expressions. In plain text, the only available grouping symbol is parentheses.
√(x+1)
Given:
Two chords intersect each other inside the circle.
To find:
The value of x.
Solution:
According to intersecting chords theorem, if two chords intersect each other inside the circle, then the product of two segments of one chord is equal to the product of two segments of second chord.
In the given circle,





Divide both sides by 2.

Splitting the middle term, we get



Using zero product property, we get
or 
or 
For
, the side AE is negative. So,
is not possible.
Therefore, the required solution is
.
