Mabc=324°. convert this degree measure to its equivalent radian measure.

9/5 π radians

Step-by-step explanation:

Set this up:

324°/1 x 2π radians/360°

You can simplify 324 to 9 and 360 to 10 (The degree sign cancels out). So:

9/1 x 2π radians/10

Then do 9 x 2/10 = 1  4/5. The improper form of this fraction is 9/5. Don't forget to include the pi sign (π) in your answer,

which is...…drum roll, please   :)

9/5 π radians

I hope this helps!  :)

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
