I believe the answer is yes because, the product will be always more than one. When anyone converts a improper fraction the decimal value is always more than ONE. therefore the fractions added/multiplied with each the answer will be more than 1...<span />
Rewriting the equation as a proportion, we have
(1/2 * 2x/2x) + (1/2x * 2/2) = (x^2 - 7x + 10)/4x
(2x/4x) + (2/4x) = (x^2 - 7x + 10)/4x
Multiplying both sides of the equation by 4x to clear the denominators:
2x + 2 = x^2 - 7x + 10
We now have a new equation that is equivalent to the original equation:
x^2 - 9x + 8 = 0
We can also write the equation into its factored form:
(x - 8)(x - 1) = 0
Now we have a product of two expressions that is equal to zero, which means any x value that makes either (x - 8) or (x - 1) zero will make their product zero.
x - 8 = 0 => x = 8
x - 1 = 0 => x = 1
Therefore, our solutions are x = 8 and x = 1.
(x+3)^2 - x^2 - 3x - 7 is the correct pattern, though it is not simplified.

Answer:
(C) 10.4 lb
Step-by-step explanation:
If Paul added each weight before adding, as you state, he got:
Apples 3.78 ⟶ 3.8
Peaches 2.12 ⟶ 2.1
Oranges 4.45 ⟶ <u> 4.4
</u>
Total 10.3 lb
If he did it this way, he did it <em>incorrectly</em>, and his answer isn't in the list of options, anyway. That's because his method introduces round-off errors.
The correct way is to add the numbers as given, and then round off <em>at the end</em>.
Apples 3.78
Peaches 2.12
Oranges <u> 4.45</u>
Total 10.35 ⟶ 10.4 lb
Note: When you drop a 5 f<em>ollowed by nothing</em>, you round off to the <em>nearest even number</em>.
