If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.
With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).
The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.
If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.

9.015 that is the decimal form, 1803/200 is fraction form.
When the first number increases by one the second number is added by 4's. So from the first part to the second it added 4 then from the 2nd to the 3rd it skips adding 8 to then just add 12. Then from the 3rd to the 4th it skips adding 16 and adds 20. So the next set of numbers would be (4,64) because it skips adding the 24 and adds the 28.
Hope this helps and is not to confusing :)
Answer:
its 3
so its
(4x+4)^2-2(4x+4)-5
so first you have to do
(4x+4)(4x+4)
the answer is 16x^2+32x+16
and then you do -2(4x+4) and then you add them so then its
16x^2+32x+16-8x-8-5
and then you just add like terms so its
16x^2+24x+3
and then you insert 0 for x
so the answer is 3

Step-by-step explanation:
1. Sinking Fund: Expenses like these are predictable. You know exactly when they’re going to come due, and you know at least approximately how much they’re going to cost"
So we have: down payment for a car, saving to start a business, saving for a college education
2. Rainy-Day Fund: unexpected expense you have to pay,
So we have: plumbing expenses, paying to fix a broken air conditioner, unexpected travel expense, plumbing expenses
