Area of the cross section (Trapezium) :
1/2 (6 + 11) x 3 = 25.5 cm²
Volume = area x height = 25.5 x 3 = 76.5 cm³
= <span>(-8x - 9)(-9x2 + 7x - 9)
= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81
= 72x³ + 25x² + 9x + 81
In short, Your Answer would be: Option D

Answer:
x = -7/12 or -0.583.. repeating.
Step-by-step explanation:
6x-5= -6(x+2)
___________ (distributive property)
(to group like terms)
6x-5 = -6x-12
___________ (addition poe) (add 6x on both sides to cancel -6 out)
+6x +6x
___________
12x-5 = -12
__________
+5 +5 (addition poe) (add 5 to both sides to cancel -5 out)
__________
12x = -7
__________
÷12 ÷12 (division poe) (divide both sides by 12 to get x)
x = -7/12

I can get it into standard form of that certain conic section by completing the square
<span>
</span>
(x^2-2x)+(y^2-4y)-31=0
<span>
</span>
(x^2-2x+1-1)+(y^2-4y+4-4)-31=0
<span>
</span>
(x-1)^2-1+(y-2)^2-4-31=0
<span>
</span>
(x-1)^2+(y-2)^2-36=0
<span>
</span>
(x-1)^2+(y-2)^2=36
<span>
</span>
(x-1)^2+(y-2)^2=6^2
in form
(x-h)^2+(y-k)^2=r^2
r=radius
so how wide it is is the diameter which is 2 times of radius
6=radius
6 times 2=12
12 inches I assume if the units in equation is in inches
