Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9

Answer:
1. D 2. B 3. C
Step-by-step explanation:
WARNING: I am not 100% sure about 2.
1. If you simplify the first part of the equation for letter D, you'll realise it is the same equation.
2. It is either B or D. I believe it is B because you would not have to multiply 4 again.
3. The square root of 121 is eleven, the square root of x^2 is x. x=11.
