Simplify x+2/x^2+2x-3 divide by x+2/x^2-x

ira [324]

$\dfrac{\frac{x+2}{x^2+2x-3}}{\frac{x+2}{x^2-x}}$

If $x\neq-2$ , then we can immediately cancel the factors of $x+2$ :

$\dfrac{\frac1{x^2+2x-3}}{\frac1{x^2-x}}=\dfrac{x^2-x}{x^2+2x-3}$

Factorize the numerator and denominator:

$x^2-x=x(x-1)$

$x^2+2x-3=(x+3)(x-1)$

Next, if $x\neq1$ , then

$\dfrac{x^2-x}{x^2+2x-3}=\dfrac{x(x-1)}{(x+3)(x-1)}=\dfrac x{x+3}$

Circumference of a Circle Formula: C = πd

Step-by-step explanation:

Step 1: Define

Circumference C = 141.3 ft

Step 2: Solve for d

Substitute in C [Circumference Formula]: 141.3 ft = πd
Substitute in π (approximation): 141.3 ft ≈ 3.14d
[Division Property of Equality] Divide both sides by 3.14: 45 ft ≈ d
Rewrite: d ≈ 45 ft
