Hey guys... Please can you tell me what the rule is for simplifying surds that are being added?

I have this seemingly simple question:

root 8 + root 18 (answer is apparently 3 root 2... I dont know how to get that answer)

If they were multiplied it would just be, put them both under one square root and work it out.

Thanks for any help :D

For a 3-quart pot of chili, use a combination of peppers and tomatoes totaling 12 items in one of the following ratios.

If the answer is in whole numbers, we want to know how many peppers and how many tomatoes we should use.

1. Which ratio is correct?

2.Then how many peppers & how many tomatoes will you actually use?

peppers tomatoes
3: 2
2: 3
2: 4

Suppose that Galileo is in the Leaning Tower of Pisa. He throws a cannonball straight down from height H above the ground. The ball leaves his hands with an initial speed Vo. At the same instant, his friend throws a cannonball straight up from ground level with an initial speed of 2Vo. When the cannonballs collide, they are traveling in the same direction and Galileo's cannonball is
traveling with 7 times the speed of his friend's. Ignore air resistance.

a. At what time does the collision occur? Express your answer in terms of H and Vo
only.
b. At what height above the ground does the collision occur? Express your answer in terms of H only
