Answer:
36 : 4
Step-by-step explanation:
40 divided into ratio 9:1 is like 40 / (9 + 1) multiplied to both sides of 9:1
40 / (9 + 1) = 4, and if you multiply both sides by 4, you get 36 : 4
I think the answer is 36
You add 9 and 1 to get 10 and then you divide 40 by 10 and get 4 and then you multiple 9 and 4 to get 36.
the answer will be A
Answer: 36 + 4d
so basically we just distribute to all the numbers in the parantheses. so 4 times 9 is 36 and 4 times d is 4d.
