3x^4-x
X(3x^3-1)
Hope it’s help you
Answer: The answer is (22, 15).
Step-by-step explanation: Given that 'x' represents the number of cars Leonard has and 'y' represents the number of cars Liam has.
Then, according to the given information, we have

Multiplying the first equation by 2 and adding to the second equation, we have

So,

Therefore, Leonard has 22 cars and Liam has 15 cars.
Thus, (22, 15) is the solution to the given system.
Common factor is 4X
Rewriting the term we get: 
Step-by-step explanation:
We need to find the common factor of the expression: 
A common factor is the term that is common in all the terms of the expression.
In the given expression the common factor is: 4X because it is common in both terms


So, Common factor is 4X
Rewriting the term we get:

Answer:
Length
inches
Width
inches
Step-by-step explanation:
Let
= length of rectangle,
= width of rectangle
Given the area and the perimeter of the rectangle, we can write:

So:



Now, we can use substitution to find the value of
:



(Quadratic equation)
∴ 
We can use substitution again to find the value of 



∵ Length usually refers to the longer side of a rectangle, ∴ length
inches and width
inches.
Hope this helps :)
