The answer is C.

First you calculate the area of the backyard:(3x-5)*(4x-10)=12x^2-50x+50

Then you calculate the swimming pool area: (x+8)*(x-2)=x^2+6x-16

Finally, you substract the swimming pool area from the total backyard area and you get:
11x^2-56x+66 which is C.

Which shows one way to determine the factors of x^3 - 9x^2 + 5x - 45 by grouping ?

adoni [48]

You can group first two conjunctions and second two:
$x^3 - 9x^2 + 5x - 45=(x^3-9x^2)+(5x-45)$ .
In first brackets you have common $x^2$ and in second brackets common is 5:
$(x^3-9x^2)+(5x-45)=x^2(x-9)+5(x-9)=(x-9)(x^2+5)$ .

42-x=58

or, -x=58-42

with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.

or, -x= 16

or,x=-16.

therefore x=-16...

Hope this helps you.
