Answer: The equation: x=-6
Step-by-step explanation: Use desmos for graphing equations
If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.
It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.
Since it has two or more places, 5 and 10 are also factors.

Let the width = x
Let the length = x + 9
Area = 52 in^2
Formula
Area = L * W
Solve
52 = (x + 9)(x ) Remove the brackets.
52 = x^2 + 9x Subtract 52 from both sides
x^2 + 9x - 52 = 0 Factor
You need 2 numbers that add to 9 and multiply to 52. There aren't many
52 and 1
26 and 2
13 and 4
All three will multiply to 52. 52 = 52 + 1 or 52 - 1 (The larger number must be plus). 53 or 51 is not the sum. 52 and 1 is not the answer.
26 and 2 will add or subtract to 28 or 24. Neither 1 is 9. So that can't be your answer.
13 and 4 will give 9 or 17. There's your answer.
(x + 13)(x - 4) = 0
x = - 13 is not the answer. You cannot have minus distances.
x - 4 = 0
x = 4
The width is 4 inches <<<< answer.
