Answer:

27

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = \frac{1}{2} × 8² - (\frac{1}{4} × 8 + 3)

     = \frac{1}{2} × 64 - (2 + 3)

     = 32 - 5

     = 27

Gnesinka [82]

Answer:

17 / 18

Step-by-step explanation:

1/9 + 5/6 needs to be converted to a different equivalent fraction so that the denominators are the same, so;

1/9 = 2/18 and 5/6 = 15/18

2/18 + 15/18 = 17/18!

Irina18 [472]

Answer:

−24

Step-by-step explanation:

Since there is only one negative, this means when all the values are multiplied together the product will be negative. Just multiply all three together to get −24.

(3)(−4)(2)

(−12)(2)

−24

It doesn't matter which order you multiply in in this case.
