we know that
Additive identity property:
If we add a real number to zero or add zero to a real number, then we get the same real number back.
The number zero is known as the identity element, or the additive identity.
For example: a+0 =a
we can see that adding gives same result
so, 0 is the additive identity here
Hence , option-B........Answer
22 unit cubes and 2 smaller cubes of volume cubic inch each
B or (0,-2) is the answer i would go with
The slope of parallel lines is equal and the slope of perpendicular lines is a negative multiplicative inverse of each other.
<h3>What is the standard equation of a line?</h3>
The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y-intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
A square is a polygon with four sides, the opposite sides are parallel and all the sides are equal, all the angles have an equal measure of 90 degrees.
Two lines are parallel to each other when they are at a fixed distance always and never intersect with each other.
The slope of the lines parallel to each other is equal.
Two lines are said to be perpendicular when they intersect at 90 degrees.
The slope of two perpendicular lines has a product of -1.
