Answer 2

It looks like you have provided three expressions, and it seems like you want to simplify them. Let's simplify each expression one by one:

1. $\frac{18a - 3a^2}{18a^2 - 48a}$

First, let's factor out the common term $3a$ from the numerator:

$3a \cdot \frac{6 - a}{18a^2 - 48a}$

Now, let's factor out $3a$ from the denominator:

$3a \cdot \frac{6 - a}{6a \cdot (3a - 8)}$

Finally, we can cancel out the common term $3a$ from the numerator and denominator:

$\frac{6 - a}{6 \cdot (3a - 8)}$

So, the simplified expression is $\frac{6 - a}{18a - 48}$.

2. $8p - 40$

This expression is already in its simplified form, as there are no like terms that can be combined.

3. $\frac{4 - x^2}{10 - 5x}$

First, let's factor the numerator, which is a difference of squares:

$\frac{(2 + x)(2 - x)}{10 - 5x}$

Now, let's factor out $5$ from the denominator:

$\frac{(2 + x)(2 - x)}{5 \cdot (2 - x)}$

We can cancel out the common factor $2 - x$ from the numerator and denominator:

$\frac{2 + x}{5}$

So, the simplified expression is $\frac{2 + x}{5}$.

To summarize:

1. $\frac{18a - 3a^2}{18a^2 - 48a}$ simplifies to $\frac{6 - a}{18a - 48}$.

2. $8p - 40$ is already simplified.

3. $\frac{4 - x^2}{10 - 5x}$ simplifies to $\frac{2 + x}{5}$.
