Soloha48 [4]

Answer:

see explanation

Step-by-step explanation:

Given

$\frac{6(2a-4c)-6(6a-4b)+3(4b-8c)}{4}$

Distribute the 3 parenthesis on the numerator

= $\frac{12a-24c-36a+24b+12b-24c}{4}$

Collect like terms on the numerator

= $\frac{-24a+36b-48c}{4}$

Divide each of the terms on the numerator by 4

= $\frac{-24a}{4}$ + $\frac{36b}{4}$ + $\frac{-48c}{4}$

= - 6a + 9b - 12c ← factor out - 3 from each term

= - 3(2a - 3b + 4c)

Compare with

X(2a + Bb + Cc) to obtain

X = - 3, B = - 3, C = 4

// program uses a for loop to exchange the contents of the second column with the fifth column in a six rows and eight columns array

public class Main{

public static void main(String[] args) {

//specifying an integer to hold values during swap

int value = 0;

//sample array of

int[][] arr = {

{1, 2, 3, 4, 5, 6, 7, 8},

};

//loop to swap column 2 and column 5

for (int i = 0; i < arr.length; i++) {

for (int j = 0; j < arr[i].length; j++) {

if(j==1){

value = arr[i][j];

}

if(j==4){

arr[i][1] = arr[i][j];

arr[i][j] = value;

}

//loop to print out result

for (int[] ints : arr) {

for (int anInt : ints) System.out.print(" " + anInt);

System.out.print("\n");
