I think you mean circumference, which is equal to = 2πr
The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.

Answer:
10
Step-by-step explanation:
Given expression is 
.
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value, 
Now, substitute in the above formula.
(since <em>i </em>= –1)
(since 
and 
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression is 10.
Answer: easy. The value is 3 tenths.
Step-by-step explanation:
Answer:
Option D.) 236 degrees
Step-by-step explanation:
Angle GFE is half of the central angle. Measure of central angle is congruent to it's intersecting arc, therefore;
<em>2 * ∠GFE = Arc GE (?)</em>
2 * 118 = Arc GE (?)
<u>236 = Arc GE (?)</u>
Hope this helps!
