X * (x + 1) * (x -4) = 84
x^2 + x * (x -4) = 84
x^3 + x^2 -4x^2 -4x = 84
x^3 - 3x^2 -4x -84 = 0

Answer:
11 inches
Step-by-step explanation:
We want to work out the radius of the cylinder in inches so we have to utilise the volume of a cylinder formula which is
Volume = π × r² × h
Where "r" is the radius and "h" is the height
→ First substitute the value into the formula
121 π = π × r² × 1
→ We can divide both sides by π to get rid of it
121 = r² × 1
→ We should divide both sides by 1 to isolate r²
121 = r²
→ Now, we can square root both sides to find the value of the radius
11 = r
→ So the radius of the cylinder is 11 inches

Step-by-step explanation:
-12 / 3 x (-8 + (-4)*2 -6) + 2
-12 / 3 x (-8 + 16 -6) + 2
-12 / 3 x (2) + 2
-4 x (2) + 2
-8 + 2

Answer:
the telephone polé is 24ft.
Step-by-step explanation:
30^2-18^2=b^2
900-324=b^2
576=b^2
\sqrt[576]=sqrt(b^2]
24=b
b=hight of telephone
