A) No triangle exists with the given side lengths.
B) Exactly one unique triangle exists with the given side lengths.
C) More than one triangle exists with the given side lengths.
According to triangle inequality theorem, “The sum of the length of two sides of a triangle should be greater than the third side”. In order to verify the mentioned theorem, some calculations are performed below.
12 + 15 > 18
15 + 18 > 12
12 + 18 > 15
As the triangle inequality theorem satisfied, so there is only one triangle possible with the given sides length. No more than one triangle is possible, because the angles are not given, and the sides length are fixed.
So option “B” is correct.
Answer:
it is b
Step-by-step explanation:
If squaredeck has an area of 81 square feet then each side of the square deck is 9 feet long.
The area of Rectangle is length times of width.
The area of a square is given by the formula A = s²
where A is the area and s is the length of each side.
In this case, we are given that the area of the deck is 81 square feet, so we can plug that into the formula:
81 = s²
To solve for s
we can take the square root of both sides:
√81 = √s²
9 = s
Therefore, each side of the square deck is 9 feet long.

All 4 sides of a square are of the same length.
The formula for the area of a square is s*s = area where s is the length of one side of the square.
s^2 = 81
s = 9 or -9
-9 does not apply here but 9 does.
Each side of the square deck is 9 feet long.

Answer:
900000
Step-by-step explanation:
3*10^5+2*10^5+4*10^5
we can start by adding the base numbers (3, 2 & 4) since they are all being multiplied by 10^5: 3+2+4=9
so then we have 9*10^5
then we solve for 10^5, which is 10*10*10*10*10 or 100000
so we then have 9*100000 and we get
900000

Answer:
The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Step-by-step explanation:
Cost of building 20 years ago = 12000000
We are given that the cost depreciated at 9% per year
Formula :
Where N(t)= Population after t years
=Initial population=12000000
r= rate of depreciation=0.09
t = 20 years
Substitute the values in the formula:
N(t)=1819738.95
Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
