3x²+12x-15=0 factrozation method quadratic equations

the answer is 8over 7

Step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
