B. 180cm3
You have to find length, width, and height of both objects.
For the first one multiply:
3 x 8 x 5 = 120
Then multiply:
2 x 5 x 6 = 60
Add them together:
120 + 60 = 180cm3
The nurse will give 12.1 milliliters of Levofloxacin
<h3>What are metric units?</h3>
These are the units that are used to measure quantities, and they can be converted among one another
The given parameters are:
- Size = 605 mg
- Dose = 50mg/5 mL
The number of milliliters the nurse will give is calculated by dividing the size by the dose, as follows:

So, we have:

Cancel out the common units

This gives

Divide 605 by 50

Hence, the nurse will give 12.1 milliliters of Levofloxacin

As it is, in accordance with the priorities of the operators (or the PEMDAS rule) the equation without parentheses mean
<span>(2/3)x+1=(1/6)x-7
I do not suppose you mean the above, since the solution is relatively trivial.
I suppose you actually mean
</span><span>2/(3x+1)=1/(6x-7)
in which case you would cross-multiply:
2(6x-7)=(3x-1)
and expand/distribute
12x-14=3x-1
isolate x and solve
12x-3x=-1+14
9x=13
x=13/9
If you mean the first form of equation without parentheses, my apologies.</span>
Would be the last answer because (n-3)times (n-3) is n^2-6n+9
