You need to add up all the sides of the thing thank you
        
                    
             
        
        
        
Answer:
1) as-16a
taknig a as common
=a(s-16)
2)as-4a³
taking a as common
=a(s-4a²)
3)2a³+8a-4a²-16
taking common terms
=2a(a²+4)-4(a²+4)
=(2a-4)(a²+4)
again taking common 
=2(a-2)(a²+4)
i hope this will help you :)
 
        
             
        
        
        
Answer:
Approximately 6.4
Step-by-step explanation:
We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c
:(5^2)+(4^2)=c^2
:25+16=c^2
:41=c^2
:sqrt(41)=6.4=c              (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!
 
        
                    
             
        
        
        
Answer:
p=−248.125
Step-by-step explanation:
- Subtract 100 on each side of the equation.
- After this, you will have 99.25=0.4p.
- Divide each side of the equation by 0.4 to get p by itself.
- You should get p= -248.125
