So exg
prime factorization is finding the prime number that will multiply to getthat tnumber
normally we exclude the number 1
so prime factor of 6=2 times 3
note:2*3 menas 2 times 3
so 891
it is odd so not divisible by 2
try 3
891/3=297
3*297=891
factor further
297
try 3
297/3=99
3*3*99=891
99
divide by 3
33
3*3*3*33
33
divide by 3
11
3*3*3*3*11
11 is prime so the prime factoization is
3*3*3*3*11 or 3^4*11

Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be
If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get
Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26
Answer:
- 4.2x - 6y + 3.6

- 2(2.1x + 3y - 1.8)
- 4.2x - 6y + 3.6
Interest earned
7,500×0.055
=412.5
Deduct tax
412.5−412.5×0.2
=330
Add the remaining interest
330+7,500
=7,830
Calculate interest earned in the second year
7,830×0.055
=430.65
Deduct tax
430.65−430.65×0.2
=344.52
Add the remaining interest
344.52+7,830
=8,174.52. ...answer
