Answer:

= ( {x}^{a}  -  {3y}^{2b} ) \times ( {x}^{2a}  +  {3x}^{a}  {y}^{2b}  +  {9y}^{4b} )

Step-by-step explanation:

{x}^{3a}  - 27 {y}^{6b}

( {x}^{a}  {)}^{3}  -  {3}^{3}  \times ( {y}^{2b}  {)}^{3}

( {x}^{a}  {)}^{3}  - (3 {y}^{2b}  {)}^{3}

( {x}^{a}  -  {3y}^{2b} ) \times (( {x}^{a}  {)}^{2}  +  {x}^{a}  \times  {3y}^{2b}  + ( {3y}^{2b}  {)}^{2} )

\boxed{\green{= ( {x}^{a}  -  {3y}^{2b} ) \times ( {x}^{2a}  +  {3x}^{a}  {y}^{2b}  +  {9y}^{4b})}}

Answer:

Area = 32 square inches

Step-by-step explanation:

It  is given that ,

1). an isosceles right triangle with a perimeter of 27 inches

Then the base and height are equal

2). the longest side measures 11 inches

<u>To find the smaller side</u>

Then sum of other 2 sides = 27 - 11 = 16

Base = height = 16/2 = 8 inches

Area = 1/2 * Base*Height

Base = 8 inches and Height = 8 inches

Area = 1/2 * 8* 8 = 32 square inches
