Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
It looks like it could be: 0 + 2 = 2 2 + 4 = 6 6 + 6 = 12 The next logical answers would be: 12 + 8 = 20 20 + 10 = 30 30 + 12 = 42 And so on...
First, factor out the coefficient of x (in this case, 4) 4x+20----> 4(x+20/4) --> 4(x+5) then, go make yourself a sandwich.
Answer : x = ± 1 4x2 - 30 = 34 : 4x2 = 34 - 30 = 4 4x2 = 4 : x2 = 1 therefore x = √1 = ± 1
They are 24 and 28.
The set is: 20, 24, 28.
The multiples of 4 up to 30 are: 4, 8, 12, 16, 20, 24, 28.

There are 30 multiples of 4 between 5 and 125. Simply divide by 4 and solve for the multiples of 1 between 1.25 and 31.25. That is a range of 2 to 31, and there are 30 multiples. (31 - 2 + 1)
The multiples of 4 that are less than 30 are 4, 8, 12, 16, 20, 24, 28
24,28,32.
10, 20, 30, 40
The multiples of 4 between 20 and 40 are numbers that can be divided evenly by 4 within that range. The multiples of 4 are 24, 28, 32, and 36. These numbers are obtained by multiplying 4 by consecutive integers starting from 6 (4 x 6 = 24) up to 9 (4 x 9 = 36).

The first 4 multiples of 10 are: 10, 20, 30, and 40.
10, 20, 30,... To get the multiples, multiply 10 by 1, 2, 3, 4, 5,...
