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!
We can solve this problem by using PEMDAS
PEMDAS stands for
Parenthesis
Exponents
Multiply
Add
Subtract
So start with (P+3) () is a parenthesis
Size bc it’s 8 numbers away
On a number line, v would be all the numbers to the left of -3 (for example, |-4|=4 which is greater than 3) and all the values to the right of positive 3. Since it can't equal 3, v=-3 and v=3 are not included on the number line.
Y = 10 degrees
work:
6y + 3 + 4y - 13 = 90
6y + 4y = 90 + 13 - 3
10y = 100
y = 10
