This is an equilateral triangle since all the sides are the same.

Hey there! :)
-(3x)² + 3 = -6
Simplify.
-(9x²) + 3 = -6
Simplify.
-9x² + 3 = -6
Subtract 3 from both sides.
-9x² = -6 - 3
Simplify.
-9x² = -9
Divide -9 from both sides.
-9x² ÷ -9 = -9 ÷ -9
Simplify.
x² = 1
So, x = 1 OR x = -1

Turn 7/10 into decimal. (0.7)
Keep adding by 0.7 until you get the number closest to 4.1
3.5 is the closest, if we add another 0.7, we get 4.2.
So, he can get 5 sections of 0.7m
