5 because 5×5= 25 and 5×5×5= 125
Pentagon is a regular polygon
Answer:
2(x -1) - 3(4 x² + 7 x +1)
(-16 x² +10 x - 3) + (4 x² -29 x -2) these expressions are equivalent to the polynomial -12 r²- 19 r -5
Step-by-step explanation:
2(x -1) - 3(4 x² + 7 x +1)
= 2 x -2 -12 x² - 21 x - 3
= -12 x² -19 x -5
This expression is equivalent to the polynomial -12 r² - 19 r -5
Another equation is
(-16 x² +10 x - 3) + (4 x² -29 x -2)
= -16 x² +10 x - 3 + 4 x² - 29 x - 2
= -12 x² -19 x - 5
This expression is also equivalent to the polynomial -12 r² - 19 r -5
From the equation, we have

To find the vertex and focus, we have to use the following formula

And

So, we have
