Answer:
A and B are both correct
Step-by-step explanation:
the definitions of the following words are:
factor- a number or quantity that when multiplied with another produces a given number or expression.
multiple- a number that can be divided by another number without a remainder.
6 multiplied with 7 equals 42
42 divided by 7 equals 6 
 another way of phrasing it:
7 and 6 are factors of 42
and
42 is a multiple of both 7 and 6

Answer:
There are 51 boxes all together.
Step-by-step explanation:
Since there are three separate, equal-size boxes, and inside each box there are four separate small boxes, and inside each of the small boxes there are three even smaller boxes, to determine how many boxes are there all together, the following calculation must be done:
3 + 3 x 4 + 3 x 4 x 3 = X
3 + 12 + 36 = X
51 = X
Therefore, there are 51 boxes all together.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Y = 1/5 x + 14 where b = 7
Result:
x + 70 = 5 Y
Geometric figure:
line
Alternate forms:
x = 5 Y - 70
x - 5 Y + 70 = 0
Real solution:
Y = x/5 + 14
Solution:
Y = x/5 + 14
Integer solution:
x = 5 n, Y = n + 14, n element Z
Solution for the variable x:
