Answer:
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
4(3+x)
This is because 4*3=12 and 4*x is 4x so you get 12+4x which is the original equation
$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)
K^2 +3k +5k + 15
k (k+3) +5 (k+3)
(k+5)(k+3)
So, the correct option is the last one.
