Answer:
X= 140
Step-by-step explanation:
f(x) = x3 – 4x² - 6x – 32 at x = 6
(6)(6)(6) -4²=72
-6(6)-32= -68
72+68=140

Answer:
B) identity property of addition.
Step-by-step explanation:
Given:
The statement given is:

Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.
So, the value of
must be 0 because on adding
to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
2,000
10,000 divided by 5 = 2,000
