Answer:
Step-by-step explanation:
<u>Plot the points to find out that:</u>
- ABCD is a rectangle with one side on the y-axis.
When rotated about the y-axis we'll get a cylinder.
The radius of the cylinder is 3 units and the height is 4 units.
Answer:
12
Step-by-step explanation:
his he had lost 12 of his marbles then he would only have 12 left to begin with.
to do this we can do the equation:
24/0.5 (the 0.5 is the represent that the 24 marbles had been split into two, a half for each party)
this would then give use our quotient of 12 marble he had lost
Step-by-step explanation:
(3x+3)(x+2)=
3x^2+6x+3x+6
=3x^2+9x+6
we get quadratic equation
find discriminant:
D=b^2-4ac=81-72=9
x=(-b±√D)/2a
x1=-6/6=-1
x2=-12/6=-2
one of the x values should be correct.
but why when I try to put values I get zero
Answer:
I would go with letter F because it's most reasonable.
Step-by-step explanation:
Each row has 4 squares.
Since three are circled it is 3/4.
So 3/4 divided by 4 is 3/16.
