A.) Prove that the ratio of two rational numbers must be rational. b.) Prove that if is irrational, and b and c are rational numbers such that , then we must have b=c=0

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

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:
