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 numbers are 18 and 38
Step-by-step explanation:
x =smaller integer and y =larger integer
Wow… how is this a question? .-.
Answer:
17/38 or ≈ 0.45
Step-by-step explanation:
(-7) -10 / (-28)-10
= -17 / -38
= 17/38
You can keep the answer in fraction as 17/38 or ≈ 0.45
Hope this help you :3
