Answer:
1. 8/35
2. 13/35
Explanation:
You add the numbers in the parentheses first, then you multiply
1. 1/5 + 3/5 = 4/5
4/5 * 2/7 = 8/35
———————————
2. 1/5 + 3/5 * 2/7
You would multiply 3/5 and 2/7 first
1/5 + 6/35
Then you find a common denominator
1/5 = 7/35
Then you add 7/35 and 6/35
7/35 + 6/35 = 13/35
Combine like terms.
-14cd + 15cd - 15cd = -14cd
-2c²d² + 9c²d² = 7c²d²
7c²d² - 14cd is your answer
