Answer:
The answer is $2.52.
Step-by-step explanation:
56 x .045= $2.52
Answer: 1- a square has 4 equal sides so if one side is 9cm then the rest are 9cm, so 9x4= 36cm
2- do the same thing as part 1 but add a power of 2 to it, so 36^2 = 1296cm
Step-by-step explanation:
<h2><u><em>Divide and subtract from both sides</em></u></h2>
Integers are closed under subtraction.
For this case we must find the inverse of the following function:

We follow the steps below:
Replace f(x) with y:

We exchange the variables:

We solve for "y":

Multiply by -2 on both sides of the equation:

We raise both sides of the equation to the square to eliminate the radical:

We subtract 3 from both sides of the equation:

We change y by f ^ {- 1} (x):
