Factor f(x)= 3x³+5x²-47x+15 into linear factors given that -5 is a zero of f(x)

Answers

Answer 1
Answer: If  -5 is a zero then f(x) is divisible by (x + 5)

the quotient when F*x) is divided by x + 5  is  :-
3x^2 - 10x + 3
this factors to 
(3x  - 1)(x  -  3)

so the answer is (x + 5)(3x - 1)(x -  3)

The year is 326 B.C. Alexander the Great stands at the
Indus River in what is now Pakistan. For a decade he and
his Greek soldiers have been battling their way across the

homesick, they refuse to go on. Alexander realizes he
cannot continue to conquer Asia, but he is too curious to stop
exploring. He has already built a fleet of eight hundred ships,
appointed his close friend Nearchus captain, and sent them
to investigate the coast of India by sea
Nearchus was the captain of a fleet of ships that
Alexander the Great had built
Alexander the Great was victorious over formidable

Two times the least of three consecutive odd integers exceeds three times the greatest by 15 What are 3 odd integers?

Answers

n, n + 2, n + 4 - three consecutive odd integers

The equation:

2n = 3(n + 4) + 15     |use distributive property

2n = (3)(n) + (3)(4) + 15

2n = 3n + 12 + 15

2n = 3n + 27    |subtract 3n from both sides

-n = 27      |change the signs

n = -27

n + 2 = -27 + 2 = -25

n + 4 = -27 + 4 = -23

Answer: -27, -25, -23.

while digging in the background, you find an old coin. its mass is 26.76 g qnd its volume is 3cm3. what is the coin made of?

Answers

While digging in the background, you find an old coin. its mass is 26.76 g qnd its volume is 3cm³. The coin is made of copper since its density is 8.92 g/cm.

The mass of an object is the weight the object occupies and the volume refers to the space occupied by the object.

The density of an object can be used to determine an object's speciation. It can be expressed by using the formula:

Density of the object = 8.92 g/cm³

Therefore, we can conclude that the coin is made of copper since its density is 8.92 g/cm³ which is approximately equal to that of the standard density of copper (8.96 g/cm³)

How do i solve -16 = -4 - 6x

Answers

Answer:

x = 2

Step-by-step explanation

The main goal of solving this equation is getting the variable by itself.

For me personally, I prefer to have the variable on the left side of the equation, so I am just going to flip it over to look like this:

-6x - 4 = -16

Next, we must eliminate the constant on the left side of the equation, which is the four. So add four to both sides to get rid of the negative four. Remember, what you do to one side, you must also do to the other!

-6x - 4 = -16

+4           +4

Now, we have this:

-6x = -12

But wait! We aren't done yet! There is still the negative six with the variable. To get rid of it, we must divide both sides of the equations by negative six, as a negative divided by a negative is a positive. There is always an imaginary one next to a variable, so if we divide the negative six by itself, we will get one! Then, the variable will be by itself!

-6x = -12

÷-6     ÷-6

Now we have: x = 2

Remember that a negative divided by a negative is a positive, so the answer is 2, not negative two!
