The length of QS is 27 units.
<u>Step-by-step explanation:</u>
In the given rectangle QRST QS and RT are the diagonals. In a triangle, the opposite sides are equal and parallel. This implies that the diagonals of a rectangle are equal.
We have obtained a quadratic equation here and solving this gives the possible values of QS.This can be solved using quadratic formula
The quadratic equation is of the form 
here a=1 b=-2 c=-3
or
putting x=3 
putting x=-1
Since a length can have only positive values QS=27 units.
Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°

Answer:
g(-4) = 3
Step-by-step explanation:
g(x) = -x - 1
g(-4) = -(-4) - 1
g(-4) = 4 - 1
g(-4) = 3
