there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
<h3>
Which expression could represent the length of the rectangle?</h3>
Remember that for a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we know that the area is:
We can factorize that expression into:
So there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)

Question says that if the diameter of the earth we're squared what would the diameter of the new planet be.
Diameter of the earth is not given so we have to ways to proceed.
Assume that diameter is d then find answer.
Or
Find diameter of the Earth from internet or book then use it to find the answer.
I will go with 2nd choice.
We know that diameter of the Earth is 7917.5 miles.
So take square of that
Hence diameter of the new planet will be 62686806.25 miles.
Answer:
2(x - 2)(2x + 1)
Step-by-step explanation:
Given
4x² - 6x - 4 ← factor out 2 from each term
= 2(2x² - 3x - 2)
To factor the quadratic inside the parenthesis
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = - 3
The factors are - 4 and + 1
Use these factors to split the x term
2x² - 4x + x - 2 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 1(x - 2) ← factor out (x - 2)
= (x - 2)(2x + 1)
Hence
4x² - 6x - 4 = 2(x - 2)(2x + 1) ← in factored form
