Answer:
Option B
27x³ – 108x² + 144x – 64
Step-by-step explanation:
(3x – 4)³
(3x – 4) × (3x – 4) × (3x – 4)
(9x² – 12x – 12x + 16) × (3x – 4)
(9x² – 24x + 16) × (3x – 4)
27x³ – 36x² – 72x² + 96x + 48x – 64
27x³ – 108x² + 144x – 64
Thus, The answer is 27x³ – 108x² + 144x – 64

h/9=7
Multiply by 9 for both sides.
h/9( 9)=7(9)
Cross out 9 and 9, divide by 9 then becomes h
h=63
Answer: A. h = 63

Angle sum is the sum of all angles (exterior and interior) while interior angle sum is sum of all interior angles.
For example a square has an interior angle sum of 90° + 90° + 90° + 90° = 360° since all his interior angles measure 90° and there are only 4 of them.
It's total sum of angles is much bigger (interior + exterior angle sum)
The exterior angle sum of an square is 4 × (360 - 90°) = 1080° and you must add the interior angle sum which is 360° so we have 1080° + 360° = 1440° and that is the total angle sum.
As you can see the interior and total sum of angles are different in size and therefore are a different things.
Hope this helps.
