Today a car is valued at $42000. the value is expected to decrease at a rate of 8% each year. choose the equation that can be used to solve the problem. a.) y=42000(1+.08)^6 b.) y=42000(1+6)^8 c.) y=42000(1−.08)^6 d.) y=42000(1−.8)^6 and then: what is the value of the car expected to be 6 years from now? this is the only question i don't understand, someone !

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

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

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