Are you sure you didn’t miss anything while writing the question?
Cause we have nothing to go off. Everybody types differently so there is no way for us to say how long he typed for, unless we were given aprox how many words he wrote in a minute or something
Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²

Answer
x =
1/√3 and
x =
-1/√3 or in decimals x = + 0.577350269 and
= - 0.577350269
Explanation
-3(3x)² + 3 = -6
-3×9x² + 3 = -6
-27x² = -6-3
-27x² = -9
x² =-9/(-27)
= 9/27
x = +√(9/27)
x = 3/√27
= 3/√9×3
= 3/3√3
= 1/√3
or in decimals x = 0.577350269
Also x = -√(9/27)
x = +√(9/27)
x = -3/√27
= -3/√9×3
= -3/3√3
= -1/√3
or in decimals x = -0.577350269
