Find the area as iff it was a rectangle, then subtract the area of the triangle in the top left corner.
Area of rectangle = 20 x 18 = 360
Area of triangle = 1/2 x 4 x 3 = 6
Area of pentagon = 360 - 6 = 354 cm^2
See picture:
So with this, we will be using proportions. To solve for x, our proportion will be 
Firstly, cross-multiply: 
Next, subtract 36 on both sides: 
Next, replace -9x with 3x-12x 
Next, factor x^2+3x and -12x-36 separately:
. After, rewrite it as 
Next, solve for x separately in the two parentheses:


Since we can't have a negative length, x = 12.
To solve for y, our proportion will be 
Firstly, cross-multiply: 
Next, just square root each side, and your answer will be (rounded to hundredths) 
In short, x = 12 and y = 10.39.
Answer:

Step-by-step explanation:
Given the geometric series:

To find:
Sum of series upto 5 terms using the geometric series formula = ?
Solution:
Formula for sum of a n terms of a geometric series is given as:

is the first term of the geometric series
is the common ratio between each term (2nd term divided by 1st term or 3rd term divided by 2nd term ..... ).
Here:



So, applying the formula for given values:

So, the answer is

The range is 25
That’s the answer
