The value of x is 4. The steps to solving the equation are to use distributive property first so that the equation then looks like this: 10x+20=5x+40
Next you would combine like terms and then the equation would look like this: 5x+20=40
Then you would use the subtraction property of equality to subtract 20 from 40 so your equation will now look like this: 5x=20
Then you use the division property of equality to divide 20 by 5 to get x=4
The correct answer you are looking for is 4 + 6i
Answer:
1
Step-by-step explanation:

1 = 5/4 x 4/3 x 3/5
Answer:
Option D) -9
Step-by-step explanation:
Here (6 , n) corresponds to an ordered pair solution that is (x , y) so we have the value of x that is 6 but we need the value of y which is f(x) so we insert the value of x into the function to get the value of n like this,

because f(x) corresponds to y and hence f(6) corresponds to n
