Mathematical processes are the steps used to determine the result of operations
- The perimeter of the rectangle is

- The area of the rectangle is

The dimension of the rectangle is given as:


<u>(1) The perimeter of the triangle</u>
This is the sum of the side lengths of the rectangle.
So, we have:

This gives

Collect like terms

Open brackets

Hence, the perimeter of the rectangle is 
<u>(2) The area of the triangle</u>
This is the product of the dimensions of the rectangle.
So, we have:

This gives

Open brackets

Collect like terms


Hence, the area of the rectangle is

Answer:
The intersection point is (2,2)
Step-by-step explanation:
First let's find the equation of f(x), using the linear model:

Using the point (0, 6), we have:

Using the point (3, 0), we have:

So we have that 
To find f'(x) (the inverse of f(x)), we can substitute f(x) by x and x by f'(x) in the equation of f(x) and then isolate f'(x):

Now, to find the intersection point, we need to calculate f(x) = f'(x):

And the y-value is:

So the point is (2,2)
Answer:
<DCA and <BCF
Step-by-step explanation:
The vertically opposite angles are the angles <DCA and <BCF. These angles are always equal.
- When two lines cross, two angles that are vertical two one another are equal.
- They are know as vertically opposite angles.
- When two straight lines cross each other, four angles are produced.
- The two vertically opposite have the same values.
Answer:
30 cm
Step-by-step explanation:
add all sides and use 7 for the bottom line because 5+2=7 and use 8 for the side because 5+3=8.
