You could do 10+9=19 and 12+7=19
P=12-x/1000
1000p=12-x
1000p-12=-x
x=12-1000p
Answer:
The answer would be 15
Step-by-step explanation:
90÷6=15
You can use Heron Formula in the calculator to output the result, but i still show you the steps on paper thro
lengths of the 3 lines: \sqrt{392} , \sqrt{676} , \sqrt{676}
s= (\sqrt{392} + \sqrt{676} + \sqrt{676})/2=35.89949494
area= \sqrt{s(s- \sqrt{392} )(s- \sqrt{676})^2 } =238
So 5,10,15,20,25,30,35,40,45 so Aylson needs 1 more bead. Because 45 beads are already used!
