Advocard [28]3 years ago
8 0

Step-by-step explanation:

{a}^{3}  +  {a}^{2} b + a {b}^{2}

[Taking a common from each term]

= a( {a}^{2}  + ab +  {b}^{2} )

as \:  {a}^{2}  + ab +  {b}^{2}  =  {(a + b)}^{2}

Hence,

= a {(a + b)}^{2} (ans)

A square is made up of an L-shaped region and three transformations of the region. If the perimeter of the square is 40 units, w
Mila [183]

Answer:

20 units

Step-by-step explanation:

This implies that the square can be divided into four equal L-shaped regions. These regions with respect to transformation forms a square.

Perimeter of the square is 40 units. Since a square has equal length of sides, thus each side of the square is 10 units.

Thus, each L-shape region has dimensions; 8 units, 5 units, 5 units and 2 units.

Perimeter of each L-shape region = the addition of the length of each side of the shape

Perimeter of each L-shape region = 8 + 5 + 5 + 2

                                                         = 20 units

Hi, It is simple:

Sin(A) = a / c

Cos(A) = b / c

Tan(B) = b / a

Sin(J) = j / i

Cos(K) = j / i

Tan(K) = k / j
