Alvin has a rectangular lawn that he is going to reseed. The length is 42 feet and the width is 25 feet. Each bag of grass seed covers 50 square feet. How many bags of grass seed will Alvin need? *

Step-by-step explanation:

The area of the lawn will be

42*25=1050 ft^2

if each bag covers 50 ft^2

1050/50=21

21 bags

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

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
