If D is the midpoint of EG, find the length of EG
Brrunno [24]

ED = x - 5 <em>given</em>

DG = 4x - 38 <em>given</em>

ED = DG <em>definition of midpoint</em>

x - 5 = 4x - 38 <em>substitution</em>

-5 = 3x - 38 <em>subtraction property of equality (subtracted x from both sides)</em>

33 = 3x <em>addition property of equality (added 38 to both sides)</em>

11 = x <em>division property of equality (divided 3 from both sides)</em>

ED = x - 5 → ED = 11 - 5 → ED = 6 <em>substitution</em>

since ED = DG, then DG = 6 <em>transitive property</em>

ED + DG = EG <em>segment addition property</em>

6 + 6 = EG <em>substitution</em>

12 = EG <em>simplified like terms</em>

Answer: 12

What is the volume of a cube with length 4 inches? V=lwh
Nata [24]
The answer is:  "64 cubic inches" ;  or, write as:  "64 in³ " .
_______________________________________________________
Explanation:

V = L * w * h ; 

  = (4 inches) * (4 inches) * (4 inches) ;  

(since a "cube" has the same length, width, and height)
  
 =  (4*4*4) inches * inches * inches) ;

 = 16 * 4 * inches³ ;

= 64 inches³ ; or, write as: "64 in³ " ; or, write as:  "64 cubic inches" .
