Answer:
Obtaining the area or perimeter is the easiest and basic skills in geometry, however, when combining several plane figures, composite shapes are formed, which can include: squares, circles, triangles, rectangles, trapezoids, etc.
To obtain the area or perimeter of this type of figures should analyze the figure and follow these steps:
STEP I
♦ Must identify which figures form the total.
STEP II
♦ Analyze if there are parts of the figures that you will not need, for example the sides that join two or more figures.
STEP III
♦ Obtain separately the areas and perimeters of each figure
STEP IV
♦Add the obtained in each figure.

Step-by-step explanation:
20%
source= 8/10 is 80% so you take the remaining 20% which is the percent of increase
Answer:
<em>x </em>= -2
<em>y </em>= 0
Step-by-step explanation:
Pretty hard process, but let me explain:
First, solve for y.
Substitute -x - 2 for y in x - y = -2:
Then, simplify both sides of the equation.
x - y = -2
x - (-x - 2) = -2
After, add -2 to both sides of the equation.
2x + 2 = -2
2x + 2 + -2 = -2 + -2
Next, divided both sides by 2.
2x/2 = -4/2
After that, substitute -2 for x in y = -x - 2:
You must simplify both sides of the equation.
y = -x - 2
y = -(-2) - 2
y = 0
Sorry if this is long and confusing, but I hope this helps!!
