X squared over x plus 2 which equals 4 over x plus 2?
x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
A number divided by 4 and then decreased by 4 is -2 What is the number?
x/4 - 4 = -2 Therefore, x/4 = -2 + 4 = 2 Therefore, x = 2 x 4 x = 8

What is the derivative of the square root of 4-x?
Use the chain rule:d/dx √(4 - x) = d/dx (4 - x)1/2= 1/2 (4 - x)-1/2 x d/dx (4 - x)= 1/2 (4 - x)-1/2 x -1= -1/2 (4 - x)-1/2 or -1/2√(4 - x)
What is 29.99 x 4 x 4 x 4 x 4 x 2 x 4 x 2 x 4 x 2 x 4 x 2 x 4 x 2 x 4 x 5 x 3 x 5 x 2 x 5 x 4 x 5 x 5 x 22 x 22 x 3 plus 30 x 3 x 30 all divided by 39.99 x 39.95?
That's a total of... 17148496850051.5
X-2 times x plus 4 divided by x squared - 4?
x-2(x)+4/x^2 -4=x-2x+4/x^2 -4=-x-4+4/x^2
What is X plus 2 equals 4?
-2
-9x5 over the square root of x plus 4?
(-9x^2/√x) + 4= [-9x^2/x^(1/2)] + 4= (-9x^2)[x^(-1/2)] + 4= -9x^[2 + (-1/2)] + 4= -9x^(2 - 1/2) + 4= -9x^(3/2) + 4= -9√x^3 + 4= -9√[(x^2)(x)] + 4= -9x√x + 4Or,(-9x^2/√x) + 4= [(-9x^2)(√x)/(√x)(√x)] + 4= [(-9x^2)(√x)/√x^2] + 4= [-9(x)(x)(√x)/x] + 4 simplify x= -9x√x + 4
X squared over x plus 2 which equals 4 over x plus 2?
x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
What are the solutions to x plus 4 equals 2?
