What are the solutions to the quadratic equation (x+3)^2=49 a)x=-2 and x=-16 b)x=2 and x=sqrt-10 c)x=4 and x=-10 d)x=40 and x=-58

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest

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.
