Answer:

x^{2}(x+4)+5(x+4)\\(x^{2} +5)(x+4).

Step-by-step explanation:

In order to be able to determine the facts of x^{3}+4x^{2}  +5x +20

you just have ti group and search for a term in common that could help you factorize into two separated terms, first, you try and factorize the first two terms:

x^{3}+4x^{2}  \\x^{2} (x+4)

Remember always trying to take out the maximum exponential possible, in this case we were able to withdraw the x^{2} and this helps us to factorize easier the second one since we already have a term that we want to have in common whic wuold be (x+4):

5x+20\\5(x+4)

Now we just put together the  x^{2} and the 5, and we multiply it by our common factor:

(x^{2} +5)(x+4).

Angle PSR measures 99°. Point S has three lines extending from it. One line extends to point P, another to point Q, and the othe
liberstina [14]

Answer:

45 degree

Step-by-step explanation:

We are given that

Angle PSR=99 degrees

Angle PSQ=(3x+18) degrees

Angle QSR=(9x-27)degrees

According to question

Angle PSR=Angle PSQ+angle QSR

Substitute the values

99=3x+18+9x-27

12x-9=99

12x=99+9=108

x=\frac{108}{12}=9

Substitute the value of x

Angle PSQ=(3(9)+18)=45^{\circ}

Hence, the measure of angle PSQ=45 degree

Emily is a songwriter who collects royalties on her songs whenever they are played in a commercial or a movie. Emily will earn $
Hitman42 [59]

Answer:

(6,2)

Step-by-step explanation:

Variable Definitions:

​x= the number of commercials

y= the number of movies

Each commercial earns Emily $50, so x commercials would earn her 50x dollars in royalties. Each movie earns Emily $150, so y movies would earn her 150y dollars in royalties. Therefore, the total royalties 50x+150y equals $600:

50x+150y=600

Since Emily's songs were played on 3 times as many commercials as movies, if we multiply 3 by the number of movies, we will get the number of commercials, meaning x equals 3y.

x=3y

Write System of Equations:

​50x+150y=600

x=3y

Solve for y in each equation:

1)  50x+150y=600

   150y=−50x+600

   y=-1/3x+4

2)  x=3y

    y=1/3x

The x variable represents the number of commercials and the yy variable represents the number of movies. Since the lines intersect at the point (6,2) we can say:

Emily's songs were played on 6 commercials and 2 movies.
