By Pythagoras Theorem:
Answer:
none
Step-by-step explanation:
"they are the same" translates to ...
x = x +2
0 = 2 . . . . . . subtract x from both sides. — a FALSE statement
There are no values of x or y that make this true.
_____
The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.
Answer: -3.5

tell if im wrong
Answer:
-16, -4
Step-by-step explanation:
x² +20x +100 -36 = 0
x² +20x +64 = 0
x² -Sx +P =0, where S= sum of roots, P=product of roots
so what 2 numbers have
S= -20 and P = 64 , ...that ul be -4, -16
or you can use factoring:
( x+16) ( x+4) = 0
x+16 = 0 , x= -16
x+4 =0, x = -4
or you can do quadratic equation, or graph ...
