I think its 2 (not sure though just a guess)
If x<0 and y>0, then the sign of the real number x-y/xy would be positive. <span>If x is negative and y is positive then x-y is negative and xy is negative. A negative number divided by another negative number would be positive. Hope this answers the question.</span>
The answer is going to be 2*sqrt(5). You have to split it into perfect squares for it to be simplified... so in this case, I had sqrt(4*5) because sqrt(4) can be simplified... so your answer would be sqrt(4)*sqrt(5) or 2sqrt(5)
4y^1 + 6y^3...so factor out the GCF for another form
2y(2 + 3y^2) <== here is one form
another form would be to multiply ur equation by a multiple of ur GCF 2, such as 4
4(4y^1 + 6y^3) = 16y^1 + 24y^3 <== another form
<span>Multiply equation A by 2. x+z=6 If you replace the z with the 2, you can add whatever the amount x is to get 6!</span>
