Answer:
In order for an equation to have an infinite number of answers,
the simplified equation should be x=x.
In evaluating the above equation, -3 inserted in the box results in this simplified equation.
The answer is therefore -3
Answer:
Step-by-step explanation:
Length of a segment between two points
and
is given by the formula,

Coordinates of extreme ends of BC and EF are,
B(1, 4), C(3, -2), E(-3, -2) and F(-1, 1)
Length of BC = 
= 
=
≈ 6.32 units
Length of EF = 
= 
=
≈ 3.61 units
The length of BC is 6.32. The length of EF is 3.61.So, BC and EF don't have the same length.
