The given expression is
2 ln a + 2 ln b - ln a
It simplifies to
ln a + ln b² = ln ab²

Let us check the given answers.
1. ln ab² - ln a   = ln (ab²)/a = ln b²
   FALSE

2. ln a + 2 ln b = ln ab²
   TRUE

3. ln a² + ln b² - ln a = ln (a²b²)/a = ln ab²
   TRUE

4. 2 ln ab = ln a²b²
   FALSE

5. ln ab²
   TRUE

Answer:
Choices 2, 3, and 5  are correct.

Factor to write an equivalent expression.(What is the Greatest Common Factor?).<br><br> −9x+15y
KengaRu [80]

Answer:

GCF is 3

Step-by-step explanation:

Given the expression -9x + 15y

First, we need to find ther individual factors

-9x = -3 *3 * x

15y = 3 * 5 * y

Since 3 is common to both factors

−9x+15y = 3(-3x+5y)

Hence the GCF is 3

Vaughn is laying sod in his backyard. A diagram of his backyard is bel ow
Orlov [11]

Answer: A=944\ ft^2

Step-by-step explanation:

You need to use the following formula that is used to find the area of a trapezoid:

A=(\frac{M+m}{2})h

Where "M"and "m" are the bases of the trapezoid and "h" is the height of the trapezoid.

Based on the information given in the exercise, you can identify that:

M=c=36\ ft\\\\m=a=23\ ft\\\\h=b=32\ ft

Knowing these values, you can substitute them into the formula:

A=(\frac{36\ ft+23\ ft}{2})(32\ ft)

Finally, you must evaluate in order to find its area. This is:

A=(\frac{59\ ft}{2})(32\ ft)\\\\A=\frac{1888\ ft^2}{2}\\\\A=944\ ft^2
