The correct value in its simplified form 32 = 32
So that we can write this expression in its correct form - it's just multiplying the <u>terms</u> outside the parentheses - for the <u>terms</u> that are inside the symbol.
<h3>Resolution</h3>
4( 5 + 3 ) = 2( 22 - 6 )
4 · 5 + 4 · 3 = 2 · 22 - 2 · 6
20 + 12 = 44 - 12
<u>32 = 32</u>
Therefore, the correct simplified form of this question is <u>32 = 32</u>. So, the equality is true.

<u>1. First find the density of your chain</u>
- Volume = displaced water volume
= Volume of Final level of water - initial level of water
= 20 ml - 15 ml = 5 ml
- Density = 66.7g / 5 ml = 13.34 g/ml
<u />
<u>2. Second, write the denisty of the chain as the weighted average of the densities of the other metals:</u>
Mass of gold × density of gold + mass of other metals × density of other metals, all divided by the mass of the chain.
Calling x the amount of gold, then the amount of other metals is 66.7 - x:



Then, there are 26.47 grams of gold in 66.7 grams of chain, which yields a percentage of:
- (26.47 / 66.7) × 100 = 39.7%

This is a question about finding the GCF or the greatest common factor for these two numbers. The real question there is what is the largest number that both 56 and 64 can be divided by and still give out integers (meaning, whole regular counting numbers). This number turns out to be 8. 56/8 = 7. 64/8 = 8. The GCF gets pulled to the outside of the parenthesis and the divided numbers remain on the inside being added together. It looks like this, 8(7+8).
