Answer:

B. \frac{17}{72}

Step-by-step explanation:

{a}^{2}  +  {b}^{3}  \\  \\  =  \bigg( \frac{1}{3} \bigg)^{2}  + \bigg( \frac{1}{2} \bigg)^{3} \\  \\  =  \frac{1}{9}  +  \frac{1}{8}  \\  \\  =  \frac{8 + 9}{9 \times 8}  \\  \\  =  \frac{17}{72}  \\

Alex787 [66]
123 5/10 becuase everything on the left side of the dcimal is a whole number and everything on the right side is a fraction. The 5 is in the 10 place so the denominator would be 10 and the numerator would be 5. Your answer is 123 5/10 or simplified, 123 1/2

Answer:

1. -19x

3. 23 -  8x

5. -18x + 2y

Step-by-step explanation:
