The “greatest common factor” of 39 and 91 is 13

<u>Solution:</u>

Given that the numbers are 39 and 91

We need to find the greatest common factor. G.C.F is the largest factor that all terms have in common.

To find out the Greatest common factor first of all we need to find the factors of each number individually

\begin{array}{l}{\text { Factors for } 39=3 \times 13} \\\\ {\text { Factors for } 91=7 \times 13}\end{array}

From the above two factors of 39 and 91 we can see the greatest common factor coming out is 13

Hence, the “greatest common factor” of 39 and 91 is 13

Answer:13

Step-by-step explanation:

First do prime factorizatio. 39=3 times 13

91= 7 times 13

Then you have to find the same number that is 13  there is no more same number so you get 13.

3x^2 -5x -2=0
Kipish [7]

Answer:

Step-by-step explanation:

1. Find two numbers that add to make the coefficient of x (in this case, -5) and that multiply to make the constant term multiplied by the coefficient of x^2 (in this case, -2 x 3 = -6)

Two numbers that work are -6 and +1

-6 x +1 = -6

-6 + -1 = -5

2. Split the middle term into the two numbers that you found.

3x^2 -6x +x -2 = 0

I've put the -6 on the left side because in our next step, when we factorise, it will be easier than having the numbers the other way around.

3. Factorise the left side by taking out common factors from each pair. The pairs I'm talking about here are '3x^2 and -6x', and 'x and -2'

3x (x-2) +1 (x-2) = 0

4. You now have two numbers both being multiplied by the term x-2. We can rearrange this equation to give us two brackets being multiplied by each other.

(3x + 1) (x-2) = 0

5. According to the Null Factor Law, if two terms are multiplied together and the result is 0, then one of those terms must be 0. Make both terms equal to 0 and solve each for x.

3x + 1 = 0              x-2 = 0

3x = -1                   x = 2

x = -1/3

6. The solutions to this equation are x = 2 and x = -1/3

C(1)=−20<br> c(n)=c(n−1)+10<br><br> Find the second term in the sequence. <br> ​
svet-max [94.6K]

Answer:

c(2) = -10

Step-by-step explanation:

The first equation says that the first term of the sequence is -20.

The second equation is saying that to find any term of the sequence, add 10 to the previous term.

c(2) = c(2-1) + 10

c(2) = c(1) + 10

c(2) = -20  + 10 = -10
