22/7× 8²=201.06
22/7× 5²=78.54
This is the correct answer: 3x^3 - x^2 + 6x - 9
Answer:
Yes, it's linear.
Step-by-step explanation:
As long as it follows Y = a + bx (It's commutative so you can swap the order)
(Note: It's not squared, square rooted, etc.)
Given:


To find:
The value of x.
Solution:
We have,

The corresponding sides of the similar triangles are proportional.

On substituting the given values, we get


Multiply both sides by 11.


Add 4 on both sides.


Divide both sides by 4.


The value of x is 12. Therefore, the correct option is D.
