(-18 + 6p)</span>
Answer: it has no solutions
Step-by-step explanation:
Factor then solve to find the complex solutions.
OK the next step is to multiply 3r -1 by -7r
this gives us -21r^2 + 7r and we write it below -21r^2 + 25r
and subtract
This gives us 18r and we bring down the -6 to give
18r - 6
Finally we divide 18r by -3r to give -6 then add - 6 to the r^2 - 7r on the top
then multiply -3r - 1 by -6 to give 18r - 6
subtraction then leaves nothing.
so the answer is r^2 - 7r - 6
Mucus coating is required for multiple functions such as protection and dealing with substances or pathogens.
Cells differentiation occurs as cells changes from a basic type to a more specialized one. Some specialized cells include:
- Muscle cells.
- Immune cells.
- Epithelial cells.
