How many school are in a year at your school? You need to figure that out before you answer the question.
(-5,0) is inside the circle
921,444 rounded to the nearest hundred thousand is 900,000. Hope I helped. =)
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
