<span>4(b-6)+19
Easily you would better start with distributing 4 to the brackets
4(b -6) = 4*b - 4*6 = 4b - 24
then add 19 to these terms, we get:
4b - 24 + 19
combine like terms (which are -24 + 19), we get:
4b - 5
That's it....
Hope that helps

-7=-9+n/8
Add 9 to both sides
2=n/8
Multiply 8 on both sides
Final Answer: 16=n
Answer:
13.5 in, or 34.3 cm.
Step-by-step explanation:
First, use the formula volume = pi * r^2 * height- you have the volume, so just solve the equation 411pi = pi * 9 * r^2 for r, and you get that r = 6.75. Since diameter is equal to 2r, multiply 6.75 by 2 to get your answer of 13.5 inches. The questions asks for the diameter in centimeters though, which makes it 34.3 cm.
Hopefully this helps- let me know if you have any questions!
