A culture of bacteria has an initial population of 74000 bacteria and doubles every 3 hours. Using the formula Pt = P0 • 2^t/d where Pt is the population
after t hours, P0 is the initial population, t is the time in hours and d is the
doubling time, what is the population of bacteria in the culture after 13 hours,
to the nearest whole number?

the distance between point a and point b is 6 units

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
