Hey!

Solution:
The ratio is FEMALES to MALES.
So its 18/16, 18:16, or 18 to 16.
~Now we need to simplify.
18:16 → 18/2:16/2 → 9:8
*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

Are they supposed to be quadratic equations? Is it x^2 +3x -4 etc?
6x + 4x+6 + 8x+3 = 63
6x+4x+8x = 63 - 3 - 6
18x = 54
x = 54/18
x = 3
Side AB = 6(3) = 18
Side AC = 4(3)+6 = 18
Side BC = 8(3)+3 = 27
F(-2) is the f(x) when x is -2. From the table, it is 1.
<em>Answer:</em>
<em> 200.52 m²</em>
<em>Step-by-step explanation:</em>
<em>A = 12² + π·6²/2</em>
<em>= 144 + 36π/2</em>
<em>= 144 + 18×3.14</em>
<em>= 144 + 56.52</em>
<em>= 200.52 m²</em>
