We have to use the order of operations to solve this equation.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

The equation:
(2+1)²

So first, let's do 2+1, since it's in parentheses and you have to do parentheses first in the order of operations.
2+1 = 3

Now all we have left is:
3²

Then exponents:
3² = 9

The answer is 9. 

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Someone pls help me answer this????? THE POINTS ARE (3,-4) And (3,5)
irina [24]
The circle goes thru the given points <span>(3,-4) And (3,5).  Since the x-coordinate does not change, the diameter lies right on the vertical line x=3.  Since the vertical distance between these points is 5-(-4), or 9, the radius is 9/2.

The standard eq'n of a circle is (x-h)^2 + (y-k)^2 = r^2

Let's subst. what we know:  we get   (x-3)^2 + (y-1/2)^2 = (9/2)^2.  Note that y = 1/2 is halfway between y=-4 and y=5.</span>

Answer:


Basic Definitions of Geometry


A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no end points.
A Ray has one end point.
. Line Segment has two end points
Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.

The Bisector of a line segment is any line, or subset of a line that intersects the segment at the midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.

8 identical pens cost £12 work out the cost of 10 of these pens
katen-ka-za [31]

Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.

So now we are going to multiply £1.5 and 10. £1.5*10=15.

The total of 10 pens is £15.

I hope this helps, if you need any additional help, just ask. I am here to help you as needed.
