Answer:
x = 3
Step-by-step explanation:
According to Euclidian theorem (x+9)^2 = 18*8
(x+9)^2 = 144 find the root for both sides
x + 9 = 12 subtract 9 from both sides
x = 3
Using pythagoras a^2 + b^2 = c^2
8^2 + 3^2 = c^2
64 + 9 = 73
The square root of 73 is 8.54
So the length of the diagonals are 8.54cm
Answer:
5/6
Step-by-step explanation:
First: 2/3=4/6
Then: 4/6+1/6=5/6
There's no single polynomial that satisfies this, but the simplest one is
