If you add 2 odd numbers together eg. 5+5 it would become an even number eg. 10.
If you add 2 even numbers together eg. 60+60 it would stay as an even number eg.120.
The product is basically the same thing as that but instead of adding the same number twice, you multiplying the number with 2 which is the same as adding two of the same numbers.

Answer:
4 kg of sugar would contain 
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
Solve for x. Cross multiply.
Divide both sides by 3
4 kg of sugar would contain crystals.
<span> Add x to both lenght and width and you get 25+x and 10+x. Set up equation with new area </span>
<span>(25+X)(10+X)=1000 </span>
<span>solve using quadratic formula
