It takes 16 minutes for 9 people to paint 8 walls.
how many minutes does it take 4 people to paint 6 walls?

4 people take 27 minutes to paint 6 walls.

Step-by-step explanation:

Since we have given that

Number of people to paint 8 walls in 16 minutes = 9

We need to find the time taken by 4 people to paint 6 walls.

We will use "Time and Work " rule :

Hence, 4 people take 27 minutes to paint 6 walls.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
