<span>Step 1. Let x be the number and 1/x be its reciprocal.
Step 2. Then, since the sum of a number and its reciprocal is 25/12.
Step 3. Multiply 12x to both sides of the equation to get rid of the denominators.
Step 4. Subtract 25x to put the equation in quadratic form

42 feet to 6 feet can be written as both ratio and a fraction:
42:6
42/6
If we look at the fraction, we can clearly see that we can simplify it:
42/6 = 7/1 = 7
So we can write the ratio in its lowest terms as 7:1.
You had $9.28 prior to making the withdrawal
-$20.51 = x - $29.79
x = $9.28
Answer: The correct answer is Choice C.
For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2
This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.
