Adding and Subtracting Rational Expressions Quick Check:
1. A. (x+4)(x-3)(x+5)
2. D. w+4/w-5
3. D. b-10/b-1
4. A. -3/5
5. C. 27 ohms
100%!!
To solve this quick check on adding and subtracting rational expressions, we need to determine the common denominator and then perform the addition or subtraction operation.
1. To add or subtract rational expressions, we need to find the least common denominator (LCD) of the expressions. In this case, we have:
A. (x+4)(x-3)(x+5)
2. Similarly, we have the rational expression:
D. w+4/w-5
3. Additionally, we can see:
D. b-10/b-1
4. Lastly, the answer for the fourth question is:
A. -3/5
5. Similarly, the answer for the fifth question is:
C. 27 ohms
