Answer:
I hope this helps!
Step-by-step explanation:
3y(5x+3)=15yx+9y
2y(2x+3)=4yx+6y
4y(x+2)=4yx+8y
3y(7x+2)=21yx+6y
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
42600-25800=16800
16800/15=1120
42600*x=100*1120
x=112000/42600=2.62%
Answer:
yes correct
Step-by-step explanation:
given
5x ≥ 3x + 4 ( subtract 3x from both sides )
2x ≥ 4 ( divide both sides by 2 )
x ≥ 2 ← is the solution to the inequality
The only value greater than 2 is 3
