It means that you add a number to 4, then multiply the result by 2. If you call the number "n", you can also write this in algebra shorthand as:2(n+4)
It is 2*(x+4)
Let the number be x:- If: 4+2x = 12 Then: x = 4
The numbers are: 48+22 = 70
The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
2(k+4)
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
It is 2*(x+4)
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.
Let the number be x:- If: 4+2x = 12 Then: x = 4
2*4 + 3*x = 34
3x + (-4) ≥ 2x + 8
Half of 18 is 9 and 5+4 = 9 so the number is 5
x+4.
4 + 2*n ≥ 20
16.5
The numbers are: 48+22 = 70
The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
