Answer:
A literal equation is an equation that consists of multiple variables or letters. 
A linear equation is an equation that consists of one variable
Step-by-step explanation:
Literal EX:
a = 1/2h(a + b)
ax + b = c
u = ak/b
Linear EX:
5(3a + 8) = 12a 
4a = 8
11(3a - 18) = 12a
 
        
                    
             
        
        
        
Answer:
   4.1 cm
Step-by-step explanation:
The segment marked x bisects the chord, so the triangle shown has legs x and 7.8, and hypotenuse 8.8.
The Pythagorean theorem can be used to find x:
   8.8² = x² +7.8²
   x² = 8.8² -7.8² = 77.44 -60.84 = 16.60
   x = √16.6
   x ≈ 4.1 . . . cm
