Answer:

f(x) = x^2 - x - 6 = x^2 + 2x - 3x - 6 = x(x + 2) - 3(x + 2) = (x - 3)(x + 2)

=> x - 3 and x + 2 are factors of f(x).

Hope this helps!

If fx = 2x^2 + 3 and g(x) = x^2 - 7 find (f - g) (x)

Semmy [17]

(f-g) (x) means to subtract g(x) from f(x)

F(x) = 2x^2 +3

g(x) = x^2

This becomes:

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

"What is the probability that the next two employees that join the office staff will take the bus"

castortr0y [4]

Answer:

The correct option is A.

Step-by-step explanation:

Consider the complete question is "The table shows the transportation method used by the employees in an office.

Transportation Number of employees

Car 18

Bus 6

Walk 6

what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.

Total number of employees = 18 + 6 + 6 = 30

The probability that the employees take the bus = $\frac{6}{30}=0.2$

The probability that the employees that join the office staff will take the bus is

$Probability=(0.2)\times (0.2)=0.04$

Therefore, the correct option is A.

What is the value of x in the equation 3.5x+5.4=19.4

kipiarov [429]

Answer: x = 4

Step-by-step explanation: To solve this equation, we could go right to our steps of subtracting 5.4 from both sides, but I would do a slightly different approach.

Since I hate working with decimals, I would get rid of them.

We can do this by multiplying both sides of the equation by 10, and remember to multiply every term by 10 to keep it balanced.

*Multiplying by 10 shifts the decimal point 1 place to the right

So we have 35x + 54 = 194 which looks a lot better.

Now subtract 54 from both sides to get 35x = 140.

Now divide both sides by 35 and x = 4.
