We have to find the graph that can be used to find the solution of :x2 -1=3
We are given an inequality we can equate this equality to a new variable 'y' such that:x2 -1 =3=y
i.e. we get a system of equations as:y=x2-1
and y=3
Hence, the solution will be the x-value of the point of intersection of the system of equations.
The point of intersection are:
(-2,3) and (2,3).
Hence, the solution of the equation is:
x=2 and x= -2.
Hence, the solution of the equation is:
x=2 and x= -2.
Answer:
Step-by-step explanation:
5²+8²=25+64=89
12²=144
5²+8²≠12²
so it is not aright angled triangle.
The total exterior angles of any polygon add up to 360 degrees.
To find the exterior angle divide 360 by the number of sides:
A hexagon has 6 sides.
Exterior angle = 360 / 6 = 60 degrees.
