Step-by-step explanation:
There are both positive and negative values to substitute for x in x2 = 9. In the positive numbers, 32 = 9, so x = 3 is a solution. In the negative numbers, -32 = 9, so x = -3 is also a solution. The solutions for x2 = 9 are 3 and -3.

Answer: No .
Step-by-step explanation:
If we make two triangles with lengths of 4 centimeters and 2 centimeters and an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.
According to the definition of congruence , if two shapes are congruent then they have equal size and shape.
i.e. they look exactly same.
It means only one triangle is possible with the given measurement .
- SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then we can say that these two triangles are congruent.
