"Factors" just means numbers in the context of multiplication - so we just need to name a pair of numbers that, when multiplied, give 8.
Those would be: 1 and 8
2 and 4
so there are two solution to this question: 1 and 8, 2 and 4!
we can also include negative numbers:
-1 and -8
-2 and -4
because a multiplication of two negative numbers gives a positive result!
Answer:
The sampling used by Britney is stratified sampling.
Step-by-step explanation:
The type of sampling used is stratified sampling.
In stratified sampling the population is divided into groups by the researcher.
Stratified sampling has the advantage that the researcher can reduce or the sample size to get results that meet a certain precision or increase the sample size to get results that are more accurate.

Answer:
21 and 28
Step-by-step explanation:
1) calling the smaller number x and the larger y we can write two equations.
x+y=49 and y+2x=70
2) by reordering the first to read x= 49-y we can then plug it in as the x in the second equation.
y+2(49-y)=70
3) we can then distribute
y+98-2y= 70
and then simplify
y=28
4) then we need to plug y back into the first equation to find the value of x
x+(28)=49
-28 -28
x = 21
5) the numbers are 21 and 28
59+61+63 is a possibility
640
128 = 1 gallon times 5 equals 640
