I believe the answer is b
54x89=4806
123x85=10,455
64x15=960
264x14=3,696
Answer: x= 2
Step-by-step explanation:
hope this helped :)
Step 1
Find the area of one equilateral triangle
Applying the law of sines

in this problem
a=b=7 cm
C=60 degrees
so

cm²
Step 2
To calculate the area of the hexagon multiply the area of one equilateral triangle by 
cm²
therefore
the answer is the option
73.5 sqrt 3cm²
X = 2 expand the brackets and then collect like terms (x's on one side) and then dived to get x on its own! :)
