(9×10)+(7×1)+(3×0.1)+(5×0.01)+(6×0.001)
Step-by-step explanation:
using
The quadratic general formula
which is
r= -b±√(b²-4ac)
---------------
2a
b= coefficient of r=3
a = coefficient of r²=2
c= constant or number without any variable=-10
r= -3±√(3²-(4×2×-10)
-----------------------
2×2
r=-3±√(9-(-80)
----------------
4
r= -3±√(9+80)
------------
4
Answer:
Multiply this measurement by two to account for both sides. Add the three separate measurements together. Because surface area is the total area of all of the faces of an object, the final step is to add all of the individually calculated areas together.
