Marco starts with a population of 10 bacteria that doubles every day for a number of days, d. he writes the expression 10(2d) to find the number of bacteria after d days. isabella starts with a population of 1 bacterium that increases 20% every day for a number of days, d. she writes the expression (1 + 0.2)d to find the number of bacteria after d days. use the drop-down menus to explain what each part of marco's and isabella's expressions mean.

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
