Step-by-step explanation:
Our polynomial is x²+30x +c with a missing value c
c should make this polynomial expression a perfect square
- Write the expression with a decreasing order of degrees
x²+ 30x+c
- write the terms as factors
x² + 2*15*x +c
- notice that the in the middle we have 2*15*x so our third term will be 15²
x²+2*15*x+15² ⇒ c = 15²=225
- arrange your perfect square
(x+15)²
In Some Occasions yes. But I would say False.
The undefined terms line and plane are needed to precisely define which mathematical term?
A) line segment
hope this helps.
For this case we have the following expression:

We eliminate the parentheses taking into account that:

We add similar terms:

Different signs are subtracted and the sign of the major is placed:

Finally, the expression is reduced to:

Answer:

Option B
