For what value of x is the rational expression below undefined?
x-4/4+x

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

rotation point l

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
