Answer:

x = -3/5 or x = 9

Step-by-step explanation:

5x^2=42x+27

Step 1: Subtract 42x+27 from both sides.

5x^2−(42x+27)=42x+27−(42x+27)

5x^2−42x−27=0

Step 2: Factor left side of the equation.

(5x+3)(x−9)=0

Step 3: Set factors equal to 0.

5x+3=0 or x-9=0

A cylinder has a radius of 12 m and a height of 9 m.

aliya0001 [1]

we are given

radius=r=12m

height=h=9m

now, we can use formula of volume of cylinder

$V=\pi r^2 h$

now, we can plug values

and we get

$V=\pi (12)^2 *9$

we get

$V=1296 \pi m^3$

so, the exact volume of the cylinder is $1296 \pi m^3$ ..........Answer
