Part b: The equivalent ratio is 3:5
Answer: (8x7) - (8x3) = 32
Step-by-step explanation:
8x4 = 32
(?x7)-(?x3)=32
(8x7)-(8x3)=32
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:
Quotient = a²+ 4a- 2
Step-by-step explanation:
(8a3+31a2-20a-5)/(8a-1)
=
<u> a² +4a-2 ⇒ quotient</u>
(8a-1)√(8a3+31a2-20a-5)
8a²- a² ⇒ Multiplying (8a-1) by a²
<u> - + </u> ⇒ Changing signs
32a²- 20a- 5
32a²- 4a ⇒ Multiplying (8a-1) by 4a
<u> - + </u> ⇒Changing signs
-16a -5
- 16a +2 ⇒ Multiplying (8a-1) by -2
<u> + - ⇒</u> Changing signs
-7 ⇒ Remainder
We follow the steps of simple division to get the quotient which is a²+ 4a- 2
We multiply (8a-1) by factors such as a², +4a and -2 to get the same terms as given in the dividend.
