Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
Answer:

Answer:
then KD would be equal?
Step-by-step explanation:
not sure, but try that
The value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2
