Answer:
A piecewise function is a function in which more than one formula is used to define the output. Each formula has its own domain, and the domain of the function is the union of all these smaller domains. We notate this idea like this:
f
(
x
)
=
⎧
⎨
⎩
formula 1 if x is in domain 1
formula 2 if x is in domain 2
formula 3 if x is in domain 3
In piecewise notation, the absolute value function is

Step-by-step explanation:
▪AB = AC - EF
= 13 cm - 7 cm
= 6 cm
▪BD = CF - DE
= 16 - 8 cm
= 8 cm
BC = EF
perimeter = CF + EF + DE + AD + AB + BC
= 16 + 7 + 8 + 10 + 6 + 7
= 54 cm
Area of triangles = 1/2 × AB × BD
= 1/2 × 6 × 8
= 48/2
= 24 cm²
Area of rectangle = CF × EF
= 16 × 7
= 112 cm²
the total area = 24 + 112
= 136 cm²

Answer:
x = 13
Step-by-step explanation:
- 4 = -17 + x
Add 17 to each side
- 4+17 = -17+17 + x
13 =x
