Answer:
Step-by-step explanation:
We have the following expression:
Here we have to group similar terms, but firstly we have to solve what is inside the second parenthesis according to the rules of algebraic operations (equal signs give as a result a positive sing and different sings gives as a result a negative sing):
This expression can be written as:
Applying common factor :
This is the result
Check the picture below.
make sure your calculator is in Degree mode.
<span>x^3 - 3(x)^2 + x - 3 < 0
х</span>²(х-3)+(х-3)<0
(x-3)(x²+1)<0
x²+1 always more than zero
therefore (x-3)(x²+1)<0 when x-3<0, x<3
Answer:
A point has no length or width.
A point indicates a location in a coordinate plane.
A plane consists of an infinite set of lines.
A line consists of an infinite set of points.
Step-by-step explanation:
True : A point has no length or width. A point in geometry is a location.
True: A point indicates a location in a coordinate plane.
False: A plane has one dimension, length. A plane has two dimensions.
False: A line has a definite beginning and end. A line goes on forever in both directions so it has infinite length.
True: A plane consists of an infinite set of lines. A plane is a flat surface extending indefinitely in all directions.
True: A line consists of an infinite set of points.A line is a connected set of infinitely many points
Answer:
$513
Step-by-step explanation:
Find 9ft multiplied by 6ft, it is 54
Do $228 ÷ 54, which is equal to 4.2 repeated
Multiply 4.2 repeated by (13.5 × 9), = 513
