To answer this question we will have to understand the nature of 
.
can be rewritten as: 
. Now, 
is an irrational number and thus any of the four operations of addition, multiplication, subtraction or division placed anywhere between any of these terms will always result in an irrational number.
The only way irrational numbers can be made rational is by dividing or multiplying the given irrational number by the same irrational number.
Answer:
3
Step-by-step explanation:
Subbing -3 for x in -x^2 - 4x, we get -(-3)^2 - 4(-3)
OR -9 +12
Final result: 3
The sum of length and width is half the perimeter, so that sum is 26 inches.
If length and width were equal, they would both be 26/2 = 13 inches. Adding 2 inches to one dimension and subtracting 2 inches from the other will keep the sum the same and make them differ by 4 inches.
The length and width are 15 inches and 11 inches, respectively.
6 is Q1, 2 is minimum, max is 18. Median you just put all numbers in order and find the middle. Q3 is in between those
Answer:
10
Step-by-step explanation:
In a polygon
interior angle + interior angle = 180°, thus
exterior angle = 180° - 144° = 36°
The sum of the exterior angles in a polygon = 360°, thus
number of sides = 
= 10
