Natasha_Volkova [10]

Answer:

<h3>d) </h3><h3>2 ({(2x)}^{2}  +  {(3y)}^{2} ) \\</h3>

Step-by-step explanation:

{(2x + 3y)}^{2}  +  {(2x - 3y)}^{2}  \\ (2x + 3y)(2x + 3y) + (2x - 3y)(2x - 3y) \\ 2x(2x + 3y) + 3y(2x + 3y) + 2x(2x - 3y) - 3y(2x - 3y) \\  {4x}^{2}  + 6xy + 6xy +  {9y}^{2}  +  {4x}^{2}  - 6xy - 6xy  +  {9y}^{2}  \\  {4x}^{2}  + 12xy +  {9y}^{2}  +  {4x}^{2}  - 12xy   +   {9y}^{2}  \\  {4x}^{2} +  {9y}^{2}   +  {4x}^{2}   +  {9y}^{2} \\ {8x}^{2}  +  {18y}^{2}  \\ 2( {4x}^{2}  +  {9y}^{2} ) \\ 2( {2}^{2}  {x}^{2}  +  {3}^{2}  {y}^{2} ) \\ 2({(2x)}^{2} + {(3y)}^{2}) \\

If j=h and k=m then which expression represents the value of g
Colt1911 [192]

Answer:

Step-by-step explanation:

as given j=h and k=m then which expression for g is

as from attached image , we can see that its look like two right angle triangle

so from lower triangle we apply the pythagorean theorem .

which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

so small triangle ΔEBD

h² +k²= g²       ---------------(1)

now from big triangle ΔABC

(j + h)² +(m + h)² =f²---------(2)

given j=h and k=m so from equation-2 we can find ,

(h + h)² +(k+ k)² =f²

(2h)² +(2k)²=f²

4h²+ 4k²= f²

4(h²+k²)= f² ----------(3)

now from equation 1 and 3 we can obtained .

4×g² =f²

take square root both side we get,

2×g=f

so g=f/2----- Answer
