If the expression is r+S*2, then you are correct in saying that the answer is 6

If the expression is r+S^2, then it would be 4+1^2 = 4+1 = 5

The difference of the two expressions is that the S*2 has been changed to S^2

S*2 = s times 2
S^2 = s squared

2/3(9a+18b)=6a+kb
bagirrra123 [75]

Answer:

4.) 12

Step-by-step explanation:

\frac{2}{3} (9a + 18b) = 6a + kb \\  \\  \implies \:  \frac{2}{3}  \times 9a +  \frac{2}{3}  \times 18b = 6a + kb \\  \\  \implies \: { 6a} + 12b = 6a + kb \\  \\  \implies \:  \cancel{ 6a} + 12b -  \cancel{ 6a} = kb \\  \\  \implies \:  12b = kb \\  \\ \implies \: k =  \frac{12\cancel b}{\cancel b}  \\  \\ \huge \implies \: k = 12
