(x - 2) ( x + 1) = 3x - 2

x² + x - 2x - 2 = 3x - 2

x² + x - 2x - 2 - 3x + 2 = 0

x² - 4x = 0

x ( x - 4 ) = 0

x - 4 = 0/x

x - 4 = 0

x = 4

Answer:

x=4

Step-by-step explanation:

(x-2)(x+1)=3x-2

x(x+1)-2(x+1)=3x-2

x^2+x-2x-2=3x-2

x^2-x-2=3x-2

x^2=3x+x-2+2

x^2=4x

x^2/x=4

x=4

Deidre is picking out some movies to rent, and she is primarily interested in documentaries and children's movies. She has narro

exis [7]

Answer: 6630

Step-by-step explanation:

Given , Number of documentaries = 17

Number of children's movies = 20

Total movies = 17+20=37

Number of combinations of r things taken out of things = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Now, the number of different combinations of 3 movies can she rent if she wants at least one documentary

= (1 documentary+2 children's movies , 2 documentary+1 children's movies , 3 documentary+0 children's movies)

$=^{17}C_1\times^{20}C_{2}+^{17}C_2\times^{20}C_{1}+^{17}C_3\times^{20}C_{0}$

$=(17)\times\dfrac{20!}{2!18!}+\dfrac{17!}{2!15!}\times(20)+\dfrac{17!}{3!14!}(1)\\\\=3230+2720+680=6630$

Hence, the number of different combinations of 3 movies can she rent if she wants at least one documentary is 6630 .

dalvyx [7]

Answer:

Terrance will need a mortgage loan of US$ 174,250

Step-by-step explanation:

1. Let's review the information given to solve the question.

Value of the house Terrance Jacobs is going to buy = US$ 205,000

Down payment Terrance can afford = 15% of the value of the house

Down payment Terrance can afford = 15% of US$ 205,000

Down payment Terrance can afford = 15% * 205,000

Down payment Terrance can afford = US$ 30,750

2. For finding the amount of the mortgage loan Terrance need for buying the house, we should do this:

Amount of mortgage loan = Value of the house - Down payment

Amount of mortgage loan = 205,000 - 30,750

Amount of mortgage loan = US$ 174,250

Terrance will need a mortgage loan of US$ 174,250
