Answer:
I believe its 102
Step-by-step explanation:
Right and Left side: 10+10+8+8= 36
36 x 2 = 72
Front and Back side: 10+10+5+5= 30
30 x 2 = 60
72+60= 102
Hope this helps :)

Answer:
(1, 14)
Step-by-step explanation:
To find the vertex, complete the square.
First, factor out the leading coefficient from the first two terms:
y = -2 (x² − 2x) + 12
Now take half of the second coefficient, square it, and add and subtract the result:
(-2/2)² = 1
y = -2 (x² − 2x + 1 − 1) + 12
Factor the perfect square:
y = -2 ((x − 1)² − 1) + 12
Distribute:
y = -2 (x − 1)² + 2 + 12
y = -2 (x − 1)² + 14
So the vertex is (1, 14).
