Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Step-by-step explanation:
The equation can be solved by squaring both sides:
We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:
The square root of 49 equals 7, but the square root of -1 is an imaginary number.
The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Answer:
Equivalent equation of is
And the number of sides does a polygon have is, n =9.
Step-by-step explanation:
Given:
The sum of the interior angles, 's' in a n-sided polygon can be determined
using the formula is: .....[1]
where n is the number of sides.
We can write the equivalent equation of [1]
Divide both sides by 180;
Simplify:
Add 2 to both sides of an equation:
Simplify, we get;
......[2]
Now, to find the value of n ;
Given: s =1260°
Substitute this value in [2] we get;
or
n = 7+2 =9
Therefore, the number of sides in a polygon is, n=9
