2csc^2 X= 3cot^2 X-1How Do You Solve This?
2csc^2 X= 3cot^2 X-1 2(cot^2x+1)=3cot^2 X-1 2cot^2x+2=3cot^2 X-1 3cot^2 X-1-2cot^2x-2=0 cot^2 X-3=0 cotX=3 1/2 tan x=1/3 1/2 So the the measurements of dimensions of triangle are; perpendicular= 1 base= 3^1/2 hypotenuse= 2 That would be a 30° angle,...

2h/5-1/5=3h/5+4/5-2h/5?
Please help me with this problem. 2h/5-1/5=3h/5+4/5-2h/5 => 2h/5+2h/5-3h/5 = 4/5 +1/5 Taking LCM on both sides => 2h+2h-3h/5 = 4+1/5 => h/5 = 5/5 => h/5 = 1 Multiply both sides by 5 => h = 5 is the answer

2less Than Twice A Number 6 A. 2-2x=6 B 2x-2=6 C.x-2=6 D.2-x=6?
Answer B (2x-2=6) represents the expression "two less than twice a number is 6". B is the correct answer. 2x-2=6. Twice a number minus two equals six.

2n - 7 = 9 What Does N = ?
If 2n - 7 = 9 then what does n equal? Britthynes, Multiply 8 x 2 and that makes 16. 16-7= 9.....meaning....8 =n They path they show you to do it in school is this: 2n-7=9 2n-7+7=9+7 2n=16 2n/2=16/2 n=8

2r-3s=-2 I Have To Solve This By Elimination And Find The Solution...
Nope . For "elimination" problems, you need as many equations (at least) as you have variables. You own one equation and two variables, so there is no solution possible.

2x + 3= 9x, What's X?
I need help. 2x+3= 9x 3=7x, so, x=3/7 2x + 3 = 9x Collect terms next to x on one side of the equality sign. Subtract 2x from both sides of the equation. 2x-2x + 3 = 9x - 2x 3 = 7x Divide both sides by...

2x + 3x - 19 = 5x - 3x + 8, What Is X?
At a birthday party, Raquel is giving out bags of candy. Simon has 2 loads, and then he wins a game and is given 3 more lots. He eats 19 pieces of candy. Jamal has the same amount of candy as...

2x + 5 Is Greater Than Equal To 11?
2x + 5 > 11 2x > 6 (subtract 5 from both sides) x > 3 (divide both sides by 2)

2x + 5x = 35. What Is X?
2x + 5x = 7x 7x = 35 35 / 7 = 5 x = 5 There seems to be dual use of "x" as a "times" operator and as a variable. Quite confusing. 5. Did that mentally :) http://google-money-system.net/google-biz-kit-review/ -- CLICK HERE :) Blurtit...

2x +5x =35. What Is X?
X=5 You start with 2x + 5x =35, this becomes &nbs p; &n bsp; 7x =35 this means that x is equal to 35 divided by 7 or 5, your answer

2x Squared + 4x Can You Use The Distributive Property To Rewrite It...
Let 2x Squared + 4x =0 2x^2 + 4x = 0 Taking 2x common you will get 2x(x+2)= 0 So either 2x = 0 or x +2 =0 x= 0/2 or x = -2 Therefore, x is any...

2x Squared Minus 3x Equals 0. What Is X?
2x^2 - 3x = 0 x(2x - 3) = 0 x = 0 will make the first factor zero. x = 3/2 will make the second factor zilch. x is 0 or 3/2

2x Subtract 3y Equals 20 What's The Value Of Y When X Equals 4?
2x-3y=20 2(4)-3y=20 8-3y=20 -3y=20-8 -3y=12 -3y/-3=12/-3 y=-4

2x(x2+15)(x2-7) What Is X?
X can be anything you want it to be. You have given an expression in x, but have not required it to be equal to anything within particular. For x = 0, x = ±√7, or for x = ±i√15, the value of the expression will be zero. For x =...

2x/3 + 1/3 = 3/4 Can You Help?
2x/3 + 1/3 = 3/4 Possibly the easiest way to do this is to multiply by the least common denominator, 12. 2x/3*12 + 1/3*12 = 3/4*12 8x + 4 = 9 (simplify) 8x = 5 (subtract 4 from both sides) x = 5/8 (divide both sides...

2x^2 - 35 = 15, Can You Solve It By Using The Square Root Property...
Solve using the square root property On simplifying we get 2x^2 = 50 so x ^2 = 25 taking squareroots of both sides we get x = 5 or x = -5

2x^2 - 3x - 2 = 0, Can You Help?
2x 2 -3x -2 = (x-2)(2x+1) = 0 The roots make the factors equal to zero. x = 2 will engineer x-2=0 2x+1 = 0 2x = -1 x = -1/2

2x^2=16. What Does The X Equals?
Lol, are they supposed to be parenthesized, cuz the answer written that way is 2.8284271... It is a non-terminating number. But i think you meant (2x) 2 which would be 2.

2x^2-3x-2=0?
2x 2 - 3x - 2 = 0 2x 2 - 3x - 2 + 2 = 0+2 2x 2 - 3x = 2 2x 2 - 3x + 3x = 2 +3x 2x 2 = 2 + 3x 2x 2 / 2...

2x^2-7x-2=0, Is This Right 7+/-sq Rt 53/4?
Let's see if your answer works. 2x 2 - 7x - 2 = 0 2(7+√(53/4)) 2 - 7(7+√(53/4)) - 2 =? 0 (substitute 7+√(53/4) for x) 2(7 2 + 2*7√(53/4) + 53/4) - 49 - 7√(53/4) - 2 =? 0 (offhand, I'd say it doesn't look...
