Hello!
In geometry there are three dimensions.
Something that is one dimensional is neither flat, wide, or tall. It is just a line.
——————————————
Something two dimensional is flat and wide but has no height. An example of this is a square.
Something three dimensional is wide and tall, and has flat faces. An example is a cube.
To answer your question something one dimensional is something that is not flat, wide, or tall, such as a line.
Hope this helped!
Answer:
the third one
Step-by-step explanation:
the absolute value of -6 is 6
Answer:
4.3
Step-by-step explanation:
6.8^2-5.3^2=x^2
AC=4.3
We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
