Answer:
Step-by-step explanation:
The total surface area of the sphere = 2πr²
Total surface area of the cylinder = 2πr²+2πrh
Total surface area of the solid = 4πr²+2πrh
r is the radius of the sphere and the cylinder
h is the height of the cylinder
Total surface area of the solid = 2πr(r+h)
If the total height of the solid is 18 cm, then r+h = 18cm
Given the Total surface area of the solid = 205π cm
205π = 2πr(r+h)
205π = 2πr(18)
205π = 36πr
205 = 36r
Divide both sides by 36
205/36 = 36r/36
r = 5.69cm
Since r+h = 18cm
5.69+h = 18
h = 18-5.69
h = 12.31cm
15x^2+21x+6 that’s the answer

Answer:
Hey Dude ok so it's g = 7 Have a nice day!
Step-by-step explanation:Simplifying
-2 = g + -9
Reorder the terms:
-2 = -9 + g
Solving
-2 = -9 + g
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Add '-1g' to each side of the equation.
-2 + -1g = -9 + g + -1g
Combine like terms: g + -1g = 0
-2 + -1g = -9 + 0
-2 + -1g = -9
Add '2' to each side of the equation.
-2 + 2 + -1g = -9 + 2
Combine like terms: -2 + 2 = 0
0 + -1g = -9 + 2
-1g = -9 + 2
Combine like terms: -9 + 2 = -7
-1g = -7
Divide each side by '-1'.
g = 7
Simplifying
g = 7
