According to Pythagoras Theorem
H^2= A^2+B^2
B= √64-49= √15
If 12c-18 is the perimeter of a regular hexagon we can divide this by 6 to get the length of one side. (12c-18)/6 = 2c-3 as an expression for one side of the hexagon.
We need an expression that is equal to 12c-18 one possible expression is just 2c-3+2c-3+2c-3+2c-3+2c-3+2c-3 would be equal to 12c-18. The other expression would also have to equal 12c-18 we can divide this expression by to then add that quotient to itself. (12c-18)/2= 6c-9. 6c-9+6c-9
a.2c-3+2c-3+2c-3+2c-3+2c-3+2c-3
b.6c-9+6c-9
c. 2c-3
The answer to the question would be 1 33/40 so it would be C.
I’m gonna bet on D. Since I answered your question. Break my ankles✨
ITS A i jus did it its bot be or c or d
