Answer:
D. 89°
Step-by-step explanation:
On the line segment "C," 89 degrees is shown in one corner. x is directly across from it, therefore being the same degrees
The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.
<h3>What is an expression?</h3>
An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
<u>Given the following variables:</u>
Substituting the given variables into the given expression, we have;
Expression = (3m - n)² + 4m.
Expression = (3(63) - 45)² + 4(45).
Expression = (189 - 45)² + 180
Expression = 144² + 180
Expression = 20,736 + 180
Expression = 20,916.

4 Answers: A, C, E, and F</h3>
================================================
Explanation:
Choice A is true assuming we have 
In this case, 
and 
--------
Choice B is false. See choice A above.
--------
Choice C is true. The sequence 
is decreasing. As n gets larger, 
gets smaller. This is because the denominator is growing larger with the numerator held constant.
--------
Choice D is false. This contradicts choice C.
--------
Choice E is true since the denominator is growing forever
This is similar to 
--------
Choice F is true due to choices C and E being true.
--------
Choice G is false because it contradicts choice F.
In a triangle, the midsegment is parallel to and half of non-intersecting side.
