(r-3)(r+6) multiply need the answer now

r^2+3r-18

Step-by-step explanation:

       r     6

r     r^2   6r

-3    -3r   -18

r^2 + 6r - 3r - 18

r^2+3r-18

r^2+3r-18

Step-by-step explanation:

(r-3)(r+6)

Multiply (distribute)

r(r+6)-3(r+6)

r^2+6r-3(r+6)

r^2+6r-3r-18

r^2+3r-18

“ 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 .
