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:
200 √17
Step-by-step explanation:
distance between two points (x,y) and (x',y')
D² = (x' - x)² + (y' - y)²
D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000
D = √680000 = √4 x 17 x 10000 = 200 √17
1/8= 0.125, -1/7 = -0.143 and -4/9= -0.444
-4/9, -0.333, -1/7, 1/8
Answer: 4096
Step-by-step explanation: 1 gallon=128 ounces, 128x32=4096
You can use the pythagorean theorem.
a^2+b^2=c^2
a=9
b=b
c=41
9^2+b^2=41^2
81+b^2=1681
b^2=1600
b=+/-40
but since this is a geometric scenario, answers will only lie in the positive real number set. That's why answer is +40 or C.
