Answer:

See explanation

Step-by-step explanation:

There are 4 red tulips and 9 white tulips in a vase.

1. You can group 1 red tulip and 9 white tulips. This group of tulips consists of

1 red tulip + 9 white tulips = 10 tulips.

If there were 4 red tulips, then

4 - 1 = 3 red tulips left.

In total,

10 tulips + 3 remaining red tulips = 13 tulips.

2. You can group 4 red tulips and 6 white tulips. This group of tulips consists of

4 red tulips + 6 white tulips = 10 tulips.

If there were 9 white tulips, then

9 - 6 = 3 white tulips left.

In total,

10 tulips + 3 remaining white tulips = 13 tulips.

What is the excluded value of x / x^2 +2x -3​
Rzqust [24]

Answer:

x = - 3 and x = 1

Step-by-step explanation:

Given the rational expression

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

The denominator of the expression cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the values that x cannot be, that is

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Thus x = 1 and x = - 3 are both excluded values
