Marcus and Tony work for Lombardo's Pipe and Concrete. Mr. Lombardo is preparing an estimate for a customer. He knows that Marcus lays a slab of concrete in 9 hours. Tony lays the same size slab in 6 hours. If both work on the job and the cost of labor is $46.00 per hour, decide what the labor estimate should be.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
