I think I know the Pentagon one. I believe it'd be 225 yd.

The rectangle is 15 multiplied by 12, which is 180. And because the triangle is not a right triangle, you can just think of it as a rectangle that was broken apart. So 3 multiples by 15, 45. Add 45 and 180 to get the answer.

(x^2−x−6x^2−8x+16)/(x2−x−12)

-3 and 4 cannot be the values of x in the given expression

The expression is given as:

$\frac{(x^2-x-6x^2-8x+16)}{(x^2-x-12)}$

Start by equating the denominator to 0

$x^2 - x - 12 = 0$

Expand the above equation

$x^2 - 4x + 3x - 12 = 0$

Factorize the equation

$x(x - 4) + 3(x - 4) = 0$

Factor out x - 4

$(x + 3) (x - 4) = 0$

Split

$(x + 3)= 0\ or\ (x - 4) = 0$

Remove brackets

$x + 3= 0\ or\ x - 4 = 0$

Solve for x

$x =- 3\ or\ x = 4$

Hence, -3 and 4 cannot be the value of x in the given expression
