Area = 1/2 base x height so you would find the area of one of the 3 larger sides which would be 12.2x6.1=74.42 then divide it by 2 which is 37.21. Then multiply it by 3 because of the other sides that are the same which gets you 111.63. Then you find the area of the bottom triangle by doing 5.3x6.1= 32.33 then divide it by 2 which is 16.165. Then you add both numbers together and you get 127.795. Answer is 127.795

Answer:

$x-5$

Step-by-step explanation:

Consider the expression

$\dfrac{3x^3-15x^2+15x-75}{3x^2+15}$

Its numerator $3x^3-15x^2+15x-75$ is equivalent to

$3x^3-15x^2+15x-75\\ \\=3x^2(x-5)+15(x-5)\\ \\=(x-5)(3x^2+15)$

Therefore, given expression can be rewritten as

$\dfrac{(x-5)(3x^2+15)}{3x^2+15}=x-5$

Note that $3x^2+15\neq 0,$ so we can divide the numerator and the denominator by non-zero expression $3x^2+15.$
