The only choice that multiplies out to give the original expression is ...
... b. 3x(x + 4)(x − 2)
_____
After you factor out 3x, you have 3x(x² +2x -8). At this point you can eliminate answers C and D because the product of the constants in the binomial factors is not -8. You can eliminate answer A because the product of binomial terms gives -2x as the linear term in the quadratic factor, not +2x.
I think the answer is A,C,F
Answer:
Solution given:
the equation of a circle is:
x²+y²-6x-2y+4=0
x²-2*x*3+3²+y²-2y+1²-1²+4=0
(x-3)²+(y-1)²=9+1-4
(x-3)²+(y-1)²=6
comparing above equation with
(a-h)²+(y-k)²=r²
we get
centre (h,k)=(3,1)
radius=√6
option first
<u>(3,1), r = </u><u>√</u><u>6</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>
Answer:
7680πyd³
Step-by-step explanation:
The formula to calculate the volume of the cylinder is πr² h
Here radius (r) = 16 yd
height (h) = 30 yd
Now
the volume is
= πr²h
= 16² * 30 * π
= 7680 π yd³
Hope it will help :)❤
