Answer:

d= -2

Step-by-step explanation:

1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 2*d+4-(10+5*d)=0

2. Pull out like factors : -3d - 6 = -3 • (d + 2)

3.Solve : -3 = 0

4. the equation has no soluton because A a non-zero constant never equals zero.

5. then Solve : d+2 = 0

6. Subtract 2 from both sides of the equation :

d = -2

Answer:

$x=3\sqrt 5\\$

$y = \sqrt {126}$

Step-by-step explanation:

By geometric mean property:

$x = \sqrt{9 \times 5} = \sqrt{45} = 3 \sqrt{5} \\ \\ by \: pythagoras \: theorem \\ \\ {y}^{2} = {9}^{2} + {x}^{2} \\ \\ {y}^{2} = {9}^{2} + {(3 \sqrt{5}) }^{2} \\ \\ {y}^{2} = 81 + 45 \\ \\ {y}^{2} = 126 \\ \\ y = \sqrt{126}$
