Order from greatest to leastest: The data below was collected by scientists measuring the sizes of beetles in inches from birth to adulthood. They need help organizing their data. Please order the measurements below from least to greatest.
3/5, 2/3, 3/10, 4/5

First covert these fractions to its decimal form.

3/5 = 0.60

2/3 = 0.66

3/10 = 0.30

4/5 = 0.80

Now it's easier to calculate & organise them in ascending order (least to greatest).

0.30 < 0.60 < 0.66 < 0.80

= 3/10 < 3/5 < 2/3 < 4/5

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
