Answer:
(a) 6ab² - 8a²b + 3ab
Step-by-step explanation:
Given: 5ab² - 12a²b + 3ab + ab² + 4a²b
In this question, we will be combining like terms.
What are like terms?
Like terms are terms with the same variables and power. For example, 2x and 4x, as well as 2a² and 4a².
Combine like terms:
5ab² - 12a²b + 3ab + ab² + 4a²b
(5ab² + ab²) + (-12a²b + 4a²b) + 3ab
6ab² - 8a²b + 3ab
1/8 of 240= 1/8 x 240. So 1/8 of 240 is 30.
Answer:
D)
Step-by-step explanation:
-12/-9=y/-4
cross multiply
-9y=48
divide by 9 on each side
y= -5.33
1/19 because the rings would be 1,3,4,5,6 respectively and then u add it up
