The LCM of any set of numbers that has a prime or a number of primes in common.  The way to find it is to factor the given number down to it's primes.

3: 3

9: 3 * 3

15: 3 * 5

The number which has been bolded is the LCM in this case 3 <<<< Answer

This is not a particularly good question to learn what it might be Try these 3 numbers.

42: 2*3 * 7

84: 2 * 2 * 3 * 7

210: 2*5 * 3 * 7

The LCM for this bunch is 2 * 3 * 7 = 42

Answer:

A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of

change than Ryan's function indicating that Daniel can pack more boxes per hour.

Step-by-step explanation:

Given

Ryan: 3 boxes per hour

Daniel: y = 4h

Required

True statement about their functions

First, we calculate Ryan's function.

In 1 hour, he can pack 3 boxes.

In hours, he can pack 3h boxes.

So, the equation is:

y = 3h

So, we have:

y = 3h ---- Ryan

y = 4h --- Daniel

Both functions represent direct proportional functions.

So, when h increases y also increases.

<em>However, Daniel's function has a greater rate of change because</em>y = 4h<em> implies that he can pack 4 boxes per hour while Ryan can pack 3.</em>
