Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
Each piece is defined over some (limited) domain. When you are evaluating or graphing a piecewise function, you only evaluate or graph the function whose domain includes the variable value of interest.
THE ANSWER IS 5 since the decimals are out of place

Step-by-step explanation:
look at the picture !
she has to paint actually 6 rectangles :
the 3 tops of the 3 stairs.
and the 3 vertical front boards (the front of each step of the stairs).
what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.
each top rectangle is clearly
82×19 (19 cm deep) = 1558 cm²
each front board is
82×12 (12 cm high) = 984 cm²
so, in total we have
3×1558 + 3×984 = 4674 + 2952 = 7626 cm²
as surface area to be painted.
