Answer:
Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches
Step-by-step explanation:
If the dictionary is a square ( all sides are equal ) the the volume is
       V = Length * Length * Length = 
       V = 3 * 3 * 3 = 27 
while if its rectangular ( all side are not equal ) shaped 
       V = Length * Width * Height (thickness)
       V = L * W * 3 = 3LW 
 
        
             
        
        
        
Every angle of a square equals 90 degrees.
2x - 4 = 90              3y + 6 = 90
2x = 90 + 4              3y = 90 - 6
2x = 94                    3y = 84
x = 94/2                     y = 84/3
x = 47                        y = 28
so x = 47 and y = 28
        
                    
             
        
        
        
10tu³ + v is the simplified form.
<h3>What is algebraic expression?</h3>
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11

Answer:
X = 10 and X = -4
Step-by-step explanation:
 (x-3)^2-38=11
 (x-3)^2 = 11 +38
 (x-3) ^2 = 49
 Taking square root on both sides
 √(x-3) ^2 = √ 49
 X-3 = +7, -7
 X = 7 +3,    X= -7+3
 X = 10        X = -4
So, it has got two solutions
