Step-by-step explanation:

Hang on ,it is already proven through given .
So The proof is of one line only
- ray FEH bisects <DFG (Given)
Hence proved .
7,265 is the average of those two numbers, though i am not sure what the sign that is mentioned is
We have that
<span>y=3x</span>²<span>+18x-21
using a graph tool
see the attached figure
the solutions are
x=-7x=1</span>
No, when you substitute it into the first equation for x and y it does not equal 36 this it's not a solution
(-3)-(3)(11)=36
-3-33=36
-36 =/ 36
