The distance between 0 to -3 would be -1, -2 ,-3. So it would be going back 3 spots on the number line.
Hope this helps!
5/(x^2-4)+2/x=2/(x-2) if we factor the leading denominator, it is a "difference of squares" of the form (a^2-b^2) which always factors to (a-b)(a+b) so we have:
5/((x-2)(x+2))+2/x=2/(x-2), to add/subtract fractions we need a common denominator, so in this case we need a common denominator of x(x-2)(x+2) so
5(x)+2(x+2)(x-2)=2(x)(x+2), perform indicated operations...
5x+2(x^2-4)=2x(x+2)
5x+2x^2-8=2x^2+4x subtract 2x from both sides
5x-8=4x subtract 4x from both sides
x-8=0 add 8 to both sides
x=8
check...
5/(x^2-4)+2/x=2/(x-2) when x=8 so
5/(64-4)+2/8=2/(8-2)
5/60+1/4=2/6
5/60+15/60=20/60
20/60=20/60
Best Answer: <span>A radical expression is any expression or equation that contains a square root. The square root symbol indicates the number inside is a radical. The number inside the square root is called the radicand. Variable numbers can also be radical expressions.
Example: </span>√x+y
√16
12+√x
√3*x²
Using the law of sins:
X/ sin(44) = 4510/sin(180-44-36)
x / sin(44) = 4510 / sin(100)
x = 3,181 yards.
