80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
