Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
Step-by-step explanation:
Option B is right perpendicular bisectors of the sides of the triangle
<h3>What circumcircle?</h3>
If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC
Therefore Option B is right perpendicular bisectors of the sides of the triangle.

Answer:
798
Step-by-step explanation:
first you do 40x20=800 then 800-6=794 then 794+4=798
X+y= -12
xy=8
y=8/x
x+8/x=-12
x^2+12x+8=0
This has no integral
