Factor the expression<br> 20g3 + 24g2 – 15g – 18
abruzzese [7]
First, put parenthesis around the first two numbers and the last two numbers. 
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis. 
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis. 
(5g+6) (4g²-3) 
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.

What is the area of this regular pentagon that has been divided into five congruent triangles?
Len [333]

Answer:

120 cm^2.

Step-by-step explanation:

The area of one triangle = 1/2 * base * height

= 1/2 * 8 * 6

= 1/2 * 48

= 24 cm^2

So area of the pentagon = 5 * 24

= 120 cm^2.

Which of the following are solutions to the equation sinx cosx = (sqrt of 3)/4? Check all that apply.
Dmitriy789 [7]

\sin x \cos x = \dfrac{\sqrt 3}{4}


2 \sin x \cos x = \dfrac{\sqrt 3}{2}


\sin 2x = \sin \frac \pi 3


2x = \frac \pi 3 + 2 \pi n \textrm{ or } 2x = (\pi - \frac \pi 3) + 2 \pi n \quad \textrm{integer } n


x = \frac \pi 6 +  \pi n \textrm{ or } x =  \frac \pi 3 +  \pi n

10 increased by the quotient of a number and 6 is 15
Makovka662 [10]
<h2>Verbal Phrase to Mathematical Phrase</h2><h3>Answer:</h3>

10 +\frac{n}{6} = 15\\

<h3>Step-by-step explanation:</h3>

Let that number be n.

The quotient of a number and 6 is \frac{n}{6}\\.

"Increased" is just another term for "plus (+)" so 10 increased by The quotient of a number and 6 is 10 + \frac{n}{6}\\

And it tells us that it is 15 so it must be 10 +\frac{n}{6} = 15\\
