:if donald were two times as old as he was five years ago, he will be ten less than two times his age now. how old is donald?

He is 30 because

30-5=25*2=50

30*2=60

60-50=10

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,
