Answer:5/28
Step-by-step explanation:
We know that 5x-3x =2x
So x(5x-3x)=x×2x
=(2x)^2
=4x^2
Which is given as 18.
X^2=18÷4
=4.5
So x=root over 4.5
Which is approximately 2.25
Answer:
The center of the circle is
.

(1)
Where:
- Center.
,
- Location of the endpoints.
If we know that
and
, then the location of the center of the circle is:



The center of the circle is
.
