Hopefully this helps
think of the symbols as crocodiles ( like a crocodile mouth)
the crocodile always wants to eat the biggest number
for example:
10>3
GOOD LUCK
Refer to the diagram shown below.
The value of z that yields the expected central area takes into account the excluded areas at both tails.
Half the tail area is α/2 = 0.08/2 = 0.04.
The central area is 1 - 0.04 - 0.04 = 0.92.
From standard normal tables, obtain
z(α/2) = 1.75
Answer: 1.75
So for this, our equation is gonna be
Firstly, reverse the signs in (x+2) 
Next, change 3x^-4 to 3/x^4, and your answer will be 
Answer:
A) 720
B) a=120
Step-by-step explanation:
A) 6 sided polygon interior angle sum is (6-2)*180=720.
B) 90+110+115+160+125+a=720, a=120
