Answer: Equilateral triangles.

Explanation: We know that in similar polygons, its all the corresponding angles are congruent. Only the set of equilateral triangles contains members that are always similar( by AAA similarity criteria) to one another as the measure of all the angles of equilateral triangle is fixed i.e. 60°.
Rest other do not have fixed measure for angles in it.

Answer:

y = 3x

Step-by-step explanation:

Let's select two points from the given graph.

(1,3) (3,9)

Now, let's use slope formula to find the slope.

m = y2-y1/x2-x1

= 9-3/3-1

= 6/2

= 3

Let's substitute/plug this value into the slope-intercept form.

y = 3x + b

We can see that the y-intercept is 0, from the graph.

b = 0

Therefore,

y = 3x

The answer would be A) 8.75 

To solve you substitute the numbers into the equation y=kx
                                                                                        350=40k 
then you would divide and get 8.75

In DEFG, what is DF?
Greeley [361]
First you need to find the X You know that since its a parallelogram opposite sides are congruent so you would do the following equation

(The work below goes vertical)
2x+3=3x-1
-3x-3I-3x-3
---------------
-x      =-4
/-1        /-1
----------------
x= 4

So now that we know x=4 we plug it into the side
4+2=6

Then you multiply is by two since df goes across the whole shape and u get 12

Hope that helps
