1. To add the fractions , we first need to find a common denominator. The denominator can be factored as . So, the common denominator is . Next, we rewrite each fraction with the common denominator and add the numerators: Therefore, the correct answer is d. .2. To subtract the fractions , we first need to find a common denominator. The denominator can be factored as . So, the common denominator is . Next, we rewrite each fraction with the common denominator and subtract the numerators: Therefore, the correct answer is b. .3. To add the fractions , we first need to find a common denominator. The denominator can be factored as . So, the common denominator is . Next, we rewrite each fraction with the common denominator and add the numerators: Therefore, the correct answer is b. .4. To add the fractions , we first need to find a common denominator. The denominator can be factored as . So, the common denominator is . Next, we rewrite each fraction with the common denominator and add the numerators:$\frac {3}{d+3} \cdot \frac {d-3}{d-3} + \frac {1}{d^{2}-9} \cdot \frac {1}{1} = \frac {3(d-3)}{(d+3)(d-3)} + \frac {1}{
