Two fractions havedenominators of x^2+ 6x + 9and x^2. What is the LeastCommon Denominator?

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. It's also known as the lowest common denominator.

The denominators of two fractions are given as:

Factoring the first expression:

It's clear there is no common factor between both denominators. Such expressions and numbers are called to be coprime.

For example, 9 and 25 are coprime, but they are not prime numbers individually.

When two numbers or expressions are coprime, the LCD is just their product.

Therefore the Least Common Denominator is:

x+14

step-by-step explanation:

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,
