Check the picture below. So,the parabola looks like so, notice the distance "p". since the parabola is opening to the right, then "p" is positive, thus is 5.

I think its b or c but my best guess would be b
The answer would be 28/7
Hope this helps

Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
Answer:
33.3 Repeating
Step-by-step explanation:
1. You already know that 33 is the whole number so you have 33.
2. 1/3 is converted to .3333333 so you put 33 before the decimal point
3. You get 33.3333333
