Answer:

B. 3x² − 10x − y

Step-by-step explanation:

To simplify this, we combine like terms:

2x - 8y + 3x² + 7y - 12x

2x has a like term with -12x; 2x-12x = -10x.  This gives us

-10x - 8y + 3x² + 7y

-8y has a like term with 7y; -8y+7y = -1y.  This gives us

-10x - 1y + 3x²

In order by power of x, we have

3x² - 10x - y

11111nata11111 [884]

Answer:

\frac{3 \times 4}{5 \times 4} x -  \frac{3 \times 5}{4 \times 5} x =  -  \frac{2 \times 4}{5 \times 4}  - \frac{1 \times 4}{5 \times 4}

\frac{12x - 15x}{20}  =  \frac{ - 8 - 4}{20}

/·20

12x-15x = -8-4

-3x= -12. /·(-1)

3x=12

x=4

erik [133]

Answer:

explanation below

Step-by-step explanation:

Large companies in most cases, buy other smaller firms to benefit from their products or to snap up the talents they have in their system. There are also cases in which such acquisitions are made to destroy competition the smaller companies present.  

This form of acquisition can be termed “killer acquisition as the larger group tends to terminate the projects of the smaller companies and shelve whatever competing innovative projects they have before they can hit the markets with them.  

This type of scenario is known to be quite pervasive and could in some ways be very detrimental to the society. When competition is eliminated, people buy whatever they see with no alternatives around and in most cases, they pay exorbitant amount of money for telco products and services.

Factor the expression below.
Gnom [1K]

Answer:

A. (x-5)(x-5)

Step-by-step explanation:

We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25

2y=-10

y=-5

So this becomes (x-5)(x-5)

Hope this helped!
