PLEASE HELP ITS URGENT

Answer 1

Hello from MrBillDoesMath!

Answer:

#1. Choice a,  m = -3

#2 Choice b, 292+13m

Discussion:  

#1:

(mx+8) (2x-4)  =  2 m x^2 - 4 m x + 16 x - 32

                       = m(2x^2)  + x( -4m+16) -32

If this expressions equals

                       = -6x^2 + 28x - 32

then 2m = -6 and -4m+16 = 28, which gives m = -3. That is Choice A.

                         

#2

Choice b:

 a(n) = 292 + 13n  , n > = 1

 a(1) = 292 + 13(1)  = 305

 a(2) = 292 + 13(2) = 292 + 26 = 318

 a(3) = 292 + 13(3) = 292 + 39 = 331

 a(4) = 292 + 4(13) = 292 + 52 = 344

The sequence a(n) values match those given in the Question.

Thank you,

MrB
