Answer:

2x(3y-4x)

Step-by-step explanation:

6xy - 8x^2

Factor out the greatest common factor of 2x

2x*3y  -2x*4x

2x(3y-4x)

£1700 is invested for 3 years at 4% per year SIMPLE interest. Work<br>out the total interest​
Crank

Answer:

$1912.27

Step-by-step explanation:

Simple interest rate formula: A = P(1 + r)^t

Simply plug in the known variables

A = 1700(1 + 0.04)³

A = 1700(1.04)³

A = 1700(1.12486)

A = 1912.27

What is the factor of k2 + k - 42
marin [14]

Answer:

(k + 7) • (k - 6)

Step-by-step explanation:

Final result :

 (k + 7) • (k - 6)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "k2"   was replaced by   "k^2".

Step by step solution :

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  k2+k-42

The first term is,  k2  its coefficient is  1 .

The middle term is,  +k  its coefficient is  1 .

The last term, "the constant", is  -42

Step-1 : Multiply the coefficient of the first term by the constant   1 • -42 = -42

Step-2 : Find two factors of  -42  whose sum equals the coefficient of the middle term, which is   1 .

     -42    +    1    =    -41

     -21    +    2    =    -19

     -14    +    3    =    -11

     -7    +    6    =    -1

     -6    +    7    =    1    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -6  and  7

                    k2 - 6k + 7k - 42

Step-4 : Add up the first 2 terms, pulling out like factors :

                   k • (k-6)

             Add up the last 2 terms, pulling out common factors :

                   7 • (k-6)

Step-5 : Add up the four terms of step 4 :

                   (k+7)  •  (k-6)

            Which is the desired factorization

Final result :

 (k + 7) • (k - 6)

If f(x)=1/2x-12 find f(-12)
bearhunter [10]

Answer:

f(-12)=-18

Step-by-step explanation:

since we are replacing the x for -12 that means we will have the equation f(-12)=1/2(-12)-12 which would give us f(-12)=-6-12 which would equal -18 so the answer for f(-12) is -18
