Answer:
Step-by-step explanation:
we know that
A perfect cube is a whole number which is the cube of another whole number or a number is a perfect cube if the cube root of that number is a whole number.
so
<u>case a)</u> 

the cube root of
is not a whole number
therefore
<em><u>The expression is not a perfect cube</u></em>
<u>case b)</u> 

the cube root of
is not a whole number
the cube root of
is not a whole number
therefore
<em><u>The expression is not a perfect cube</u></em>
<u>case c)</u> 

therefore
<em><u>The expression is a perfect cube</u></em>
<u>case d)</u> 

the cube root of
is not a whole number
therefore
<em><u>The expression is not a perfect cube</u></em>
<u>the answer is</u>

- Hypotenuse=H=12in
- Perpendicular=P=7in
- Base=B=?
Using Pythagorean theorem
