A. Median. That is simply what it is called
<span>The length is:
the square root of [ (the difference in 'x' values)² + (the difference in 'y' values)² ]
D = √ [ (-2-6)² + (5-2)² ]
= √ [ (-8)² + (3)² ]
= √ (64 + 9) = √75 = 5√3 = <u>8.66</u> (rounded to 3 sig-figs)</span>

Answer:
2x^2+14x-240=0
Step-by-step explanation:
Remember Pythagoras's theorem?
a^2+b^2=c^2
So over here,
x^2+ (x+7)^2= 17^2 [ we need to now simplify (x+7)^2 --> (x+7) (x+7) ]
x^2+ x^2+7x+7x+49= 289
2x^2+ 14x+49= 289
2x^2+14x+49=0 [ we need to make the right side zero coz thats
the rule for ]
2x^2+14x-240=0
(idk, but i think the "show that x^2.....) is wrong)
