2. En cada caso siguiente, coloque el signo de elación de orden que corresponda para la pareja de números dados, o sea, los signos mayor que >, menor que <, o el signo igual =
a) 3/9 y 8/15 b) -150 y -40 c)-2/3 y 6/9 d) -10/7 y-4/3​

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

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
