Answer:

You MUST use parentheses around denominator 8+x, or ANY denominator that consist of more than a single number of variable.

Also, don't use lower case and upper case interchangeably.

In algebra, x and X are different, as are y and Y.

f(x) = y = 3x/(8+x)

Switch x and y, solve for y:

x = 3y/(8+y)

x(8+y) = 3y

8x+xy = 3y

8x = 3y−xy

8x = y(3−x)

y = f⁻¹(x) = 8x/(3−x)

Answer:

Area= 12 units squared, Perimeter= 16.12899

Step-by-step explanation:

$AC= \sqrt{(4-0)^{2}+ (0+4)^{2}} = 4\sqrt{2}$

$AB= \sqrt{(0-4)^{2}+ (2-0)^{2} } = 2\sqrt{5}$

$BC= \sqrt{(0-0)^{2}+ (2+4)^{2} }= 6$

So, perimeter= $4\sqrt{2} + 2\sqrt{5} +6= 16.12899$

$Area= \frac{1}{2}bh\\$

$= \frac{1}{2}BC\sqrt{(4-0)^{2}+(0-0)^{2} }$

$= 12$ $units^{2}$
