Answer:
Step-by-step explanation:
(2x-1)²=x²+4²
4x²-4x+1=x²+16
3x²-4x-15=0
a=3 b=-4 c= -15
D=b²-4ac
=16-4*3*(-15)=196
x1=-b+√D/2a=4+14/6=3
x2=-b-√D/2a=4-14/6=-10/6=-5/3
For this type of question, we have to take out the percentage of each candidate:
For Arthur
85 from 95
Convert 95 to 100
That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got 90% For Miguel 64 from 76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%
