Answer:
9
Step-by-step explanation:
(10x1/2) + 1/2 (-2x1/2)
-> 5+ 1/2 (-1)
-> 5+-1/2
->4.5
-> 4.5^2=9
Step-by-step explanation:
[tex]s = 10 \times \frac{1}{2} + \frac{1}{2} + ( - 2)( \frac{1}{2} ) ^{2} [/tex]
[tex]s = 5 + \frac{1}{2} \times ( - 2)(0.25)[/tex]
[tex]s = 5 + \frac{1}{2} ( -1)[/tex]
[tex]s = 5 - 0.5[/tex]
[tex]s = 4.50[/tex]
