Answer:
Step-by-step explanation:
The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.
3 / 8 = x / 10 Multiply both sides by 10.
3 * 10 / 8 = x Multiply first
30/8 = x Divide next. You don't need to do it in this order.
3 6/8 Simplify
3 3/4 Give another choice
3.75
The length = 3.75 inches
If none of these are correct, please leave a note with your choices.

Step-by-step explanation:
so i am confused what exactly do you want me to do?
<h2>Steps:</h2>
So for this, I will be completing the square to solve for x. Firstly, add 10 and subtract 30x on both sides of the equation:
Next, we want to make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and square the quotient. Once you get that result, add it to both sides of the equation:
Now, factor the left side:
Next, square root both sides:
Now, add 15 to both sides of the equation:
This is the <em>exact</em> solution. To find the approximate solution, solve the left side twice -- once with the plus sign, once with the minus sign:
