<span>The diagonals of a rectangle have equal lengths. Since AC has a length of 28,
and AC is a diagonal, the other diagonal BD also has a length of 28.
The diagonals of a rectangle also bisect each other. So diagonal BD is
bisected by the other diagonal AC at point E. And since diagonal BD has
a length of 28 then BE and ED both have a length which is of 28,
or 14 each.
Answer: ED has a length of 14.</span>
Answer:
Step-by-step explanation:
If we want to convert 
into a radical simplified, we need to find two numbers that multiply to be -50 and one of them can be squared.
The square root of -25 is 5i.

a)
Add the score and then square the sum.
By using the summation notation we can write the above statement is (Σx)²
b)
Square each score and then add the squared values.
By using the summation notation we can write the above statement is Σx²
Subtract 2 point from each score and then add the resulting values.
By using the summation notation we can write the above statement is Σ(x-2)
Subtract 1 point from each score and square the resulting values. Then add the squared values.
By using the summation notation we can write the above statement is Σ(x-1)²
