We know a or b != 0
but a-b==0 so both are the same unknown number
b/a must = 1
so
a/b is equivalent to b/a as a/b=1 as well.
So the last answer choice.
The value of expanding (2x -3)^4 is 16x^4 + 96x^3 +216x^2 -216x + 81
<h3>How to expand the expression?</h3>
The expression is given as:
(2x -3)^4
Using the binomial expansion, we have:

Evaluate the combination factors.
So, we have:

Evaluate the exponents and the products

Hence, the value of expanding (2x -3)^4 is 16x^4 + 96x^3 +216x^2 -216x + 81

This just wants the derivative which you can solve for.
You can do this using a negative expononet or using ...the rational rule forget its name*.... you shoudl get 9000/(t+12)^2

The original price of phone is $ 315.76
<em><u>Solution:</u></em>
Given that Mica bought a new smart phone for $ 258.13.
That was the price after his 18.25% discount
<em><u>To find: original price of phone</u></em>
From given question,
price after discount = $ 258.13
discount = 18.25 %
Let "x" be the original price of phone
price after discount = original price - discount




Thus original price of phone is $ 315.76
Answer:

Step-by-step explanation:

Let the linear approximation be L(x) at a = 0. This is given by

is the derivative of
. To find this, we use the form
If
, then 
By doing this and applying chain rule for the power (which is a function of x), we have

Then
