Answer: 
Step-by-step explanation:
Given
Here the given figure can be divided into two shapes i.e. rectangle and a trapezium
For rectangle ABCD Area = 
Area of trapezium CEFD Area is ![\frac{1}{2}[\text{sum of non-parallel sides}]\times[\text{distance between them}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%5Ctext%7Bsum%20of%20non-parallel%20sides%7D%5D%5Ctimes%5B%5Ctext%7Bdistance%20between%20them%7D%5D)
![\Rightarrow \frac{1}{2}\times [10+17][10]=135\ cm^2](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B10%2B17%5D%5B10%5D%3D135%5C%20cm%5E2)
Total shaded area 
We must assume that he must put a whole number of objects in each wreath so we must find the greatest common factor
60=2 time 2 times 3 times 5
36=2 times 2 times 3 times 3
48=2 times 2 times 2 times 2 times 3
the factors are 2 times 2 times 3 or 12
there can be 12 wreath max
we total them up and divide by 12
60+36+48=144
144/12=12
12 items per wreath
D because it keeps on going up 10 times per month
Answer:
(9 ^ 3) x 0.04 (4/99)
Step-by-step explanation:
This seems overwhelming, but after simplifying, it will look much easier
Numerator (First Row)
First, we will combine like terms and simplify the top row
(9 ^ <em>x</em> + 1) x 8 - (9 ^ <em>x</em> - 1) x 81
(9 ^ <em>x</em> + 1) - (9 ^ <em>x</em> - 1) x (8 x 81)
(9 ^ 2x) x 648
Denominator (Second Row)
Next, we can combine like terms and simplify the second row
(9 ^ <em>x</em>) x 66 - (9 ^ <em>x</em> - 2) x 243
(9 ^ <em>x</em>) - (9 ^ <em>x</em> - 2) x (66 x 243)
(9 ^ 2x + 2) x 16,038
Simplify
Our expression is now
(9 ^ 2x) x 648
(9 ^ 2x + 2) x 16,038
We can simplify it as
(9 ^ 3) x 0.04 (4/99)
