Answer:
what is LaTeX
Step-by-step explanation:
Volume of a cylinder = the area of the base x height of the cylinder
Area of base =

r^2
A = 6^2(

)
A = 36

V = 36

x 12
V = 432

5 cylinders = 5V
5V = 5 x (432

)
5V = 2160

Final answer: Alex needs to buy 2160

or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.

Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36
