38.A
Step-by-step explanation:
hope makatulong.
31. I use phytagorean formula
- d=√(x²-x¹)²+(y²-y¹)²
36. this the formula:x²+y²=r²
(5√3)²= 25×3 = 75
37. (11)²=121
38. (x-3)²+(y+2)²=25
-x×x=x²
(-6x) -3+(-3)=-6x
(-3)²=9
y×y=y²
2+2=4y
(2)²=4
x²+y²-6x+4y+9+4=25
x²+y²-6x+4y+9+4-25=0 - > 9+4=10-25=-12
x²+y²-6x+4y-12=0
