True. The only area where a line parallel to one side would be able to intersect both other sides would be in a place that proportionally divides the other sides.
Answer: 5
This is because (4r + 6) means you take r and multiply that number by 4.
Because there is no number, r would equal one in this case.
4 • 1 is 4
4 + 6 is 10
This would give us 1/2(10)
Half of 10 is 5.
Therefore, the answer is 5.
ANSWER
The vertex is (-2,1)
EXPLANATION
We want to find the vertex of

We complete the square to obtain,

The first three terms forms a perfect square trinomial.

The vertex form is

This equation is in the form;

where (h,k)=(-2,1) is the vertex.
First you want to reduce the brackets
Next you want to factor out the common number 3
Next you want to factor 20 + x^3 + 11x - 8x^2 by using the polynomial division method/technique
Lastly you just factor x^2 - 9x + 20 to get the answer.
Yes you are correct, the solutions are 1, 4, and 5.
