Answer:

b is -6 or -10

Step-by-step explanation:

\frac{1}{b}  =  \frac{1}{b  - 12}  +  \frac{ {b}^{2}  + 16b + 48}{ {b}^{2}  - 12b}  \\  \\  \frac{1}{b}  =  \frac{b + ( {b}^{2}  + 16b + 48)}{b(b - 12)}  \\  \\ b   - 12= b  + ( {b}^{2}  + 16b + 48) \\  {b}^{2}  + 16b + 60= 0 \\ (b + 6)(b + 10) = 0 \\ b =  - 6 \\ and \\ b =  - 10

Solve 20x+ 5y = 15 for y.
Nesterboy [21]

20x+ 5y = 15

Move 20x to the other side. Sign changes from +20x to -20x

20x-20x+5y=-20x+15

5y=-20x+15

Divide both sides by 5

5y/5=y ( Cross out 5 and 5, divide by 5, 1*1*y=y)

-20/5=-4x

15/5=3

y=-4x+3 or y=3-4x

Answer: y=-4x+3 or y=3-4x

Need help.please on number one
professor190 [17]
The answer is 12 including both sides and angles.

When you cut a square piece of paper from one point to the opposite point it should make two triangles.

Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides

So 12, sides and angles added together.
