Volume = Length x Length x Length
Volume :
(x + 2) (x + 2) (x + 2)
= (x² + 4x + 4)(x + 2)
= x³ + 2x² + 4x² + 8x + 4x + 8
= x³ + 6x² + 12x + 8
Answer: x³ + 6x² + 12x + 8
Answer:
the answer is 67.44 hope it helps smile
For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)
<span>= ( 0, 12) </span>
<span>AC = 12 </span>
<span>B - C = (7 - 3) - ( - 2 -3) </span>
<span>= (9, 0) </span>
<span>BC = 9 </span>
<span>ABC is a right -angled triangle with AC as the hypotenuse </span>
<span>AC = sqrt( 9^2 + 12^2) </span>
<span>= sqrt(81 + 144) </span>
<span>= srqt(225) </span>
<span>= 15 </span>
<span>Perimeter = 12 + 9 + 15 </span>
<span>= 36 units </span>
<span> So the answer is 36 units
</span>I hope my answer helped you.

Answer:
centre = (13,0)
radius = 8
Step-by-step explanation:
The standard equation of the circle is
(x-x0)^2 + (y-y0)^2 = r^2 ...............(1)
where
(x0,y0) is the centre,
r is the radius.
For
(x-13)^2 + y^2 = 64 ..............(2)
we rewrite (2)
(x-13)^2 + (y-0)^2 = 8^2 ...............(3)
and compare (3) with (1)
to identify
x0 = 13, y0 = 0, and r = 8
Therefore
centre = (13,0)
radius = 8
