The difference of two numbers is 16 and the sum of their squares is 130. What are the numbers.
Korvikt [17]
x - y = 16
x^2 + x^2 = 130

----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108

Help!!!!!!!!!!!!!!!!!!!!
lapo4ka [179]
Well...   the segment FG = 4x + 3, the segment GH = 7x - 12, now, the
 
segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.

thus, FG = GH
or

\bf 4x+3=7x-12\implies 3+12=7x-4x\implies 15=3x&#10;\\\\\\&#10;\cfrac{15}{3}=x\implies \boxed{5=x}\\\\&#10;-------------------------------\\\\&#10;thus\qquad &#10;\begin{cases}&#10;\overline{FG}=4x+3\\&#10;4(5)+3\\&#10;23\\&#10;------\\&#10;\overline{GH}=7x-12\\&#10;7(5)-12\\&#10;23&#10;\end{cases}\impliedby equal\ halves&#10;\\\\\\&#10;\overline{FH}=23+23\implies \overline{FH}=46\implies 6y-2=46&#10;\\\\\\&#10;6y=46+2\implies y=\cfrac{48}{6}

and fairly sure, you know how much that is.
