Regular shapes are shapes that have sides that are all equal and interior angles are also equal.
Irregular shapes are shapes that vary in the measurement of sides and interior angles.
To find the area of an irregular shape, break it down into various regular shape and individually compute its area. Add up all the area of the regular shapes formed from the irregular shape to get the area of the irregular shape.
An example of an irregular shape is the outline of a house.
Pointed roof over a square room. There are two regular shapes found in this irregular shape. A square and a triangle. Compute its individual area and add up these two areas to get the area of the house.
Answer:
41
Step-by-step explanation:
x=12
so y=3⋅12 +5
=36+5
=41
Answer:
We have:
x < 4 AND x > a.
if a = 4 and we use an "or" instead of the "and" we have:
x < 4 or x > 4.
This is:
"x is larger than 4 or smaller than 4."
Then the solution of this is all the real numbers except the value x = 4.
The set of solutions can be written as:
{xI x ∈ R \ [4]}
Where this reads:
"x belongs to the set of the reals minus the number 4".
Or we also could write it as:
x ∈ (-∞, 4) ∪ (4, ∞)
Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.
