...Sin^4X/Cos^4X + Sin^2X/Cos^2X =Sin^4X/Cos^4X + Cos^2X.Sin^2X/Cos^4X =Sin^2X/Cos^4(Sin^2X + Cos^2X) =Sin^2X/Cos^4X =(1-Cos^2X)/Cos^4X =1/Cos^4X - Cos^2X/Cos^4X =1/Cos^4X - 1/Cos^2X =Sec^4X - Sec^2X ...

2x=5+4(-1/2) so 2x=(10-4)/2 so 2x=6/4 so x =3/2 The value of x=3/2 and value of y= -1/2 Let me know if you need further assistance. Thanks for using FixYa. Hello : Simplifying 5x + 3y = 6 Solving 5x +

...4-2) = 2x =>2x=-3 ; +3's moved on the right-hand side, so it becomes -3 =>x=-3/2 ; 2 has been moved to the right-hand side and divided with -3 i.e 1/2 multiplied by -3 = -3/2 Hence, x = -3/2 ...

...2x+4=0 math problem Easy to verify. Put 4 instead of x in the equation. You get 2*4+4?=0. Obviously 2*4+4=3*4=12, and 12 is not equal to zero. The value x=4 is not a solution of the equation.2x+4=0, ...

...2x/3+4=2x I need to know how to work texas instrument TI-30xa for this equation 2x/3+4=2x Unfortunately, the TI-30Xa calculator does not handle algebraic expressions.If you are interested in knowing ...

2x = 8 x = 4 so the perimeter is 3 times either expression above 3 * (8 + 5) = 39 . Since side a = side b = side c, 4x - 3 = 2x + 5 4x - 2x = 5 + 3 2x = 8 x = 8 / 2 = 4 Therefore each side = 2*4 + 5 =

...2x 2y - 2 = 2 (4) 2y - 2 = 8 2y - 2 + 2 = 8 + 2 2y = 10 2y/2 = 10/2 y = 5 2y - 2 = 2(-4) 2y - 2 = -8 2y -2 + 2 = -8 + 2 2y = -6 2y / 2 = -6 /2 y = -3 The results are the same, implying that they are ...

4-log(2x+3\4)=0 easy: 2log(x) + log(3/4) - log(2x + 3/4) = 0 log(x^2) + log(3/4) = log(2x + 3/4) log(3/4*x^2) = log(2x + 3/4) 3/4*x^2 = 2x + 3/4 multiply equation by 4: 3x^2 = 8x + 3 3x^2 - 8x - 3 = 0
