Answer:
x³-3x²-4x
Step-by-step explanation:
x(x+1)(x-4)=x(x²-3x-4)=x³-3x²-4x
Answer:
Option A:
x^2 + (y - 2)^2 = 9
Step-by-step explanation:
We know that the equation for a circle centered in the point (a, b) and of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
So the first thing we need to find is the center of the circle.
We can see that the center is at:
x = 0
y = 2
Then the center is at the point (0, 2)
Now we want our circle to pass through point 2, located at a distance of 2 units from the radius of the first circle.
So the distance between the center and point 2 is 2 units plus the radius of the smaller circle:
And the radius of the smaller circle is one unit.
Then, the radius of a circle centered at (0, 2) that passes through point 2 is:
R = 1 + 2 = 3
Then we have a circle centered at (0, 2) and of radius R = 3
Replacing these in the equation for a circle we get:
(x - 0)^2 + (y - 2)^2 = 3^2
x^2 + (y - 2)^2 = 9
The correct option is A
Answer: 196 m
Step-by-step explanation:
The cartesian plane is composed of four quadrants: quadrant I, II, III<span> and IV. Quadrant I has positive x and </span>y axes<span>. Quadrant II has negative </span>x axis<span> and </span>y axis<span>. Quadrant III has both negative x and </span>y axes<span> while quadrant IV has </span>positive x axis<span> and negative </span>y axis<span>. x value refers to the abscissa while y value refers to ordinate. Answer hence is A</span>
7x-4=3x+ 8
-3x of both sides 4x-4=8
plus 4 to both sides 4x=12
12 divide by 4 = 3
hopeful that helps
