Answer: C. 18 square unit.
Step-by-step explanation:
Since, By the diagram we can say that,
The polygon is made by 4 rectangles in which,
Measurements of these rectangle are, 3 × 1, 4 × 1, 1 × 3, 4 × 2.
Thus, the total area of the given polygon = Total sum of the Area of these rectangles
A= 3 × 1 + 4 × 1 + 1 × 3 + 4 × 2= 3+4+3+8=18 square unit.
Thus, The area of given rectangle = 18 square unit.
Therefore Option C is correct.
Hi there!
Here are all the steps into multiplying these 2 parentheses :
(9x + 2y) × (9x - 2y)
9x × 9x = <u>81x²</u>
9x × -2y = <u>-18xy</u>
2y × 9x = <u>18xy</u>
2y × -2y = <u>-4y²</u>
81x² - 18xy + 18xy - 4y²
-18xy + 18xy = 0
Your answer is: 81x² - 4y²
There you go! I really hope this helped, if there's anything just let me know! :)

I think you forgot to give us the list
Answer:
The third side must be smaller than 20 inches and greater than 4 inches
Step-by-step explanation:
Let a, b and c be the lengths of triangle's sides. Then
Use this rule in your case. So, if a=12 and b=8, then
Hence, you get
From these inequalities, you can state that
So, c must be smaller than 20 inches and greater than 4 inches.
