Answer:
Equilateral triangle
Step-by-step explanation:
When all the sides are the same or equivalent in a triangle, the triangle is called an equilateral triangle.
Answer:
-2/1 or -2
Step-by-step explanation:
On the graph plot the points, draw a line to connect them, draw a right triangle, the up will be the 2 and the across is the 1. It is negative b/c it slopes down to the right.

Not sure if this is how your teacher wants it, but here is how I would approach it in high school geometry:
To find the area of a rectangle, you need the base and the height.
The radius is 28 mm however the radius only covers half of one circle. Multiply 28 by 2 to get the length of one circle (56) and multiply 56 by 2 to get the length of your base of your rectangle (112).
Now to find the height: the center of the circles creates an equilateral triangle with the side length of 2r or 56 in this case. This means each angle of that triangle is 60 degrees, and when split in half, this creates two triangles both with angles of 30, 60, and 90. The altitude of this triangle is r√3 because of the “special right triangle rule” or 28√3 in this case. This comes to 48.497 mm. To find the remaining length of the height, you can use the radii of the top and bottom circle which add to 56. Add this to the previous number. So...
Height: 104.497
Base: 112
Now multiply the base times height to get:
216.497 mm.
Hope that helps!
We have been given Marley was asked to solve 
using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.
We are asked to determine whether Marley is correct or not.
We know when an equation is in form 
, we can use discriminant to check for the real solutions of equation.
If 
, then the equation will have two real solutions.
If 
, then the equation will have one real solution.
If 
, then the equation will have no real solutions.
Let us find discriminant.
Since 
, therefore, the equation will have no real solutions, so Marley is correct.
Answer:
the table gives the cost for the number of three pounds bag of clemintines we need to change the number of bags to pounds to get the data or clemintines in units of pounds and cost.
