Start with the bottom surface area, 7x7=49

then go to the triangles, base times height divided by 2, so (7x14)/2=49
and since there are 4 triangles, multiply 49 by 4 = 196 and add the area of the bottom, which all adds up to 245

Answer:

- \frac{27}{7}

Step-by-step explanation:

Given

f(x) = \frac{3}{x+2} - \sqrt{x-3}

Evaluate f(19) by substituting x = 19 into f(x)

f(19) = \frac{3}{19+2} - \sqrt{19-3}

       = \frac{3}{21} - \sqrt{16}

       = \frac{1}{7} - 4

       = \frac{1}{7} - \frac{28}{7} = - \frac{27}{7}
