Apply the distributive property to factor out the greatest common factor. 15+21=15+21=15, plus, 21, equals

Step-by-step explanation:

We are asked to factor out the given expression using distributive property.

First of all, we will find greatest common factor of 15 and 21.

Factors of 15: 1, 3, 5, 15

Factors of 21: 1, 3, 7, 21.

We can see that greatest common factor of 15 and 21 is 3.

Factor out 3:

Therefore, the factored form of our given expression would be .

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
