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

Is it possible to find a value of $x$ so that the value of the surface area (in square inches) is equal to the value of the volu
Annette [7]

The box has volume

11 in × 3 in × <em>x</em> in = 33<em>x</em> in³

and surface area

2 (11 in × 3 in + 11 in × <em>x</em> in + 3 in × <em>x</em> in) = (66 + 28<em>x</em>) in²

The volume and area have the same value if

33<em>x</em> = 66 + 28<em>x</em>

Solve this equation for <em>x</em> :

33<em>x</em> - 28<em>x</em> = 66

5<em>x</em> = 66

<em>x</em> = 66/5 = 13.2
