Answer 1

Answer:

The mathematical terms that cannot be defined for all cases in a system of geometry are the parallel lines and midpoint of a line segment. A line is an infinite series of points in a row and it does not occupy any space. They are also called one dimensional since the direction is in one dimension. A point has a location but no specific size. It can describe a location but you can never determine its actual size. Imagine the point at the end of the previous sentence. And then imagine it getting smaller and smaller until it disappears. We can only use a dot to represent the point.

Answer 2

Answer:

Answer:

1. parallel lines

2. midpoint of a line segment

Step-by-step explanation:

The mathematical terms that cannot be defined for all cases in a system of geometry are:

1. parallel lines and

2. midpoint of a line segment.

A parallel line cannot be defined as lines do not occupy any space. It is a straight one-dimensional figure with no thickness and it extends infinitely in both directions.

The points also do not have any dimensions like length, area, volume, etc.

Which shows the unsimplified solution for x2 + 8x + 6 = 0?

Answers

$x^2 + 8x + 6 = 0 \n \n x^2 + 8x + 16 + 6 -16 =0\n \nx^2 + 8x + 16 -10=0\n \nx^2 + 8x + 16=10\n \n (x + 4)^2 = 10\n \nx + 4 = √( 10 ) \ \ or \ \ x + 4 = - √(10) \n \nx = √(10)-4 \ \ or \ \ x = -4 - √(10 )$

Multiply: (4x – 7)(2x – 9)

Hello there!

Let's use foil.

First: 4x * 2x = 8x^2

Outside: 4x * -9 = -36x

Inside: -7 * 2x = -14x

Last: -7 * -9 = 63

Now, let's combine these.

8x^2 - 36x - 14x + 63

Finally, we can simplify this

8x - 50x + 63

I hope I helped!
