An amoebas divides into two amoebas after one hour. one hour later each of the two amoebas divides to form two more.
write an expression for the number of amoebas after 6 hours
write an expression for the number of amoebas after 24 hours
why might exponential notation be preferable to answer these questions?

after 6 hours    2 × 2 × 2 × 2 × 2 × 2 = 2⁶

after 24 hours 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2²⁴

Exponential notation is preferable because its easier to write, and easier to work with

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
