Because it is an isosceles triangle, the two longer sides are the same length. Therefore multiply 6.3 times 2. 
To find the length of the base subtract 12.6 from 15.7 to get 3.1 cm.
        
                    
             
        
        
        
Answer:
opiton b
Step-by-step explanation:
To find out which equation satisfies h(x) we need to check with each option
We plug in x  value
A) h(–1.25) = –0.5
Plug in -1.25 for x  in h(x) = 16^x
That is not true
B) h(–0.5) = 0.25
Plug in -0.5 for x  
That is true.
C)  h(0.75) = 12
Plug in 0.75 for x  
That is not true.
D)  h(1.25) = 20
Plug in 1.25 for x  
That is not true
 
        
             
        
        
        
Answer:
f(1)=16
Step-by-step explanation:
f(t)=-16t+32t
f(1)=-16(1)+32(1)
f(1)=-16+32
f(1)=16
 
        
                    
             
        
        
        
Answer:
This would be a regular polygon.
Step-by-step explanation:
A regular polygon has congruent sides and interior angles.
An irregular polygon does not have congruent sides and all interior angles.
A convex polygon does not have a interior angle greater than 180°.
Lastly, a concave polygon has only one interior angle greater than 180°.
Using the process of elimination, it would not be a convex or concave polygon. Now we have either a regular or irregular polygon. This polygon can not be a irregular polygon because all the sides are congruent. This means that this polygon is a regular polygon!
