Answer:
Clare is correct
Step-by-step explanation:
For two shapes to be congruent, the shape and size have to be the same. In other words they ate have to equal length in size and also equal angles(same shape hence equal angles). Therefore Clare is correct since only have equal length in sides does not qualify the polygon to be congruent or similar like Priya claims
Answer: The value of a is 1. The value of b is -1. The value of c is 1. The value of the discriminant is -3. The quadratic function will not intersects the x-axis.
Explanation:
The standard form of a quadratic equation is,

The given function is,

It can be written as,

By comparing this equation with the standard form of quadratic equation. we get,



The formula for discriminant is,




The value of the discriminant is -3.
If D<0, it means the function have no real roots.
If D=0, it means function have one real roots.
If D>0, it means function have two real roots.
Since D<0 it means the function have no real roots. So the function will not intersect the x-axis at any point.
