Answer:
The answer is
<h2>length = 7.5 in</h2>Step-by-step explanation:
Area of a rectangle = length × width
From the question
Area = 90 in²
Width = 12 in
To find the length substitute these values into the formula and solve for the length
We have
90 = 12l
Divide both sides by 12
We have the final answer as
<h3>length = 7.5 in</h3>Hope this helps you

Answer:
Option D)Neither solution is extraneous.
Step-by-step explanation:
we have
we know that
two possible solutions are x=-7 and x=1
<u><em>Verify each solution</em></u>
Substitute each value of x in the expression above and interpret the results
1) For x=-7
----> is true
therefore
x=-7 is not a an extraneous solution
2) For x=1
----> is true
therefore
x=1 is not a an extraneous solution
therefore
Neither solution is extraneous
