No,The room is not a square shaped.This is because.Perimeter of the square shape would be length of any sides×4 as all sides will be the same in a square.Therefore, if the room ia a square, the 4 sides of room floor will be equal too.It is not a square shaped room beacause it sides are not equal for floor.We can determine by finding the sides;
diagonal is 18.75 so by using pythagoras theorem
diagonal^2 =l^2 + b^2
b^2=18.75^2 + 17^2
b =25.31 inches which is not the same as the length 17 inches.Therefore,the room is not a square
200x3=600
85x3=255
600+255=855
855-80=775
775x10=7,750
Answer:
65
Step-by-step explanation:
use the following equation
aₙ=a₁+(n-1)d
Where d is the common difference
n is the term
a₁ is the first term
the common difference is -3 (149-152)
this means we have
152+(30-1)*-3
Compute this and get
65
Answer:
501/200
It told me I need more characters so here’s some random letters hehehajajjajaja
(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
