The answer is B trust me I know I did that before
Answer:
x^3 - x
Step-by-step explanation:
x(x^2 + x - 1) - x^2 =
= x^3 + x^2 - x - x^2
= x^3 - x
By using the concept of line, coplanar, non parallel lines always intersect
Definition of perpendicular and skew lines has been given
What is a line?
A geometrical object which has only length but no breadth and height is called a line
The lines which are coplanar and are not parallel will intersect at some point
Two lines are said to be perpendicular to each other if the angle between them is 90°
The lines which are not parallel, non coplanar at do not intersect are called skew lines.

Answer: x ≈ 6.86°
Step-by-step explanation:
Firstly, set them equal to each other:
(7x + 24) = 72°
Subtract 24 from both sides:
7x = 48°
Divide both sides by 7:
x ≈ 6.857...
This can be rounded to:
x ≈ 6.86°
4x3=12. Think of it like this... 4 times as many as 3 is 12 (x)
(=)
So 4 times is 4 multiplied by....... 3 is just 3.... is means equals.... and the answer is 12. Your welcome, I hope I helped.
