O A = 0; B = 1; C = 3; D = -3
O A = 1; B = 0; C = -3; D = 3
O A = 1; B = 0; C = 3; D = -3

i dont get it. where are the "descriptions"?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
