Step-by-step explanation:
"identity" means an operation that does nothing.
For adding numbers, adding 0 changes nothing, so 0 is the identity for addition.
For multiplication, multiplying by 1 changes nothing, so 1 is the identity for multiplication.
Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
X(x - 2)(x - 4)
x(x² - 6x + 8)
x³ - 6x² + 8x
4x^2-5x-14 is your answer :)
A rational number is any number that can be turned into a fraction....it can be negative or positive.
Therefore, -12/6 is a rational number
