Answer:
34
Step-by-step explanation:
x=3+√8
y =3-√8
now,
1/x^2+1/y^2
=1/(3+√8)² + 1/(3-√8)²
= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)² [L.C.M = (3+√8)²(3-√8)² ]
=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²
=[6²-2.(3²-√8² )] / (3²-√8²)² [ a²+ b²=(a+b)²-2ab]
=[36-2(9-8) ]/ (9-8)²
=[36-2.1] / 1²
=34
Answer:
$7.54 is the right answer
Answer: 35, 31, 25, 18
Step-by-step explanation:
Answer:
2/9 boxes.
Step-by-step explanation:
6 / 1 / 3 = 4 / b
Cross multiply the two
6b = 4/3
Multiply 1/6 on each side
B = 4 /18
It can be reduced to 2/9.
