Answer:
18 + 81 = 9(x² + 6x + 9) 11 = (x + 3)²
Explanation:
because This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18 + 9 (9) = 9 (x² + 6x + 9)
18 + 81 = 9 (x² + 6x + 9)
99 = 9 (x² + 6x + 9)
Dividing both sides by 9, we have:
11 = x² + 6x + 9
11 = (x + 3) ²
A beaker about two-thirds full of a liquid. check all that apply. pour using tongs. wear chemical resistant gloves. taste to make sure it is hcl. One should wear chemical resistant gloves.
It is not at all possible to pour the liquid with the help of tongs because it may spill and cause harm, in case it is hazardous.
Also tasting whether the liquid is hcl or not is not gonna help because we don't know whether the chemical is fatal or not. Even if it is Hcl, tasting it is not a good option, because it will cause damage to our tongue and other parts of mouth.
Thus the most convenient thing to do is to wear chemical resistant gloves to ensure safety.

The following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
<h3>How to calculate the mole ratio</h3>
The formula for calculating the mole ratio is expressed according to the formula shown:
Mole ratio is the ratio of the mass of a substance to the molar mass of the same substance.
To calculate the mole ratio
Mole = Mass(g)/molar mass(g/mol)
Hence the following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
