To solve this expression, we need to follow the order of operations (BEDMAS)
50+0.5(41-32)
=50+0.5(9)
=50+4.5
=54.5
Your answer is 54.5
The circumference of a circle is equal to the diameter times pi. So, let's look at what happens if you double the radius of a circle -- say from 2 to 4. The area will go from 12.56 to 50.24. This means that it has quadrupled.

Answer:
∠A = ∠D (**but very important Δ ABC has to be congruent to Δ DEF)
Step-by-step explanation:
It will help if you draw the triangles out and label the same sides. Then according to the side-angle-side (SAS) rule, ∠A should be equal to ∠D
Answer:
The expression of the ellipse is: 
Step-by-step explanation:
The equation of a ellipse can be written by the following expression:
Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:
The length of the major axis is the distance between the two vertices.
![2a = \sqrt{[2 - (-2)]^2}\\2a = \sqrt{(2 + 2)^2}\\2a = \sqrt{4^2}\\2a = 4\\a = 2](https://tex.z-dn.net/?f=2a%20%3D%20%5Csqrt%7B%5B2%20-%20%28-2%29%5D%5E2%7D%5C%5C2a%20%3D%20%5Csqrt%7B%282%20%2B%202%29%5E2%7D%5C%5C2a%20%3D%20%5Csqrt%7B4%5E2%7D%5C%5C2a%20%3D%204%5C%5Ca%20%3D%202)
Therefore the expression of the ellipse is:
