Answer:
22.5 quarts
Step-by-step explanation:
Let us find the ratio of orange juice to apple juice. The punch requires 2 quarts of orange juice mixed with 5 quarts of apple juice.
The ratio of orange juice to apple juice is therefore:
2 : 5 or 2/5
Max has 9 quarts of orange juice. By comparing with the ratio, this implies that:
2 / 5 = 9 / x
x = (9 * 5) / 2 = 22.5 quarts
He will need 22.5 quarts of apple juice.
Answer:
a = 3
Step-by-step explanation:
First start writing out the binomial expansion of 
![[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]](https://tex.z-dn.net/?f=%5B1%5E7%5D%20%2B%20%5B7C1%20%2A%201%5E6%20%2A%28ax%29%5D%20%2B%20%5B7C2%2A1%5E5%2A%28ax%29%5E2%5D%2B%5B7C3%2A1%5E4%2A%28ax%29%5E3%5D)
as you can see from this, the last bracket will produce our
term
