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,

Answer:
The median is four.
Step-by-step explanation:
First you put the numbers in order from least to greatest and write the number as many times as indicated.
2 2 2 3 4 4 4 4 6 6 7 7 7 8 9
then start from one side then go to the other crossing out numbers. So cross out a two, then nine, then another two, then eight, then the last two, then the first seven and so on. When your done you should be left with one middle number, in this case it's four.
<span>F is the midpoint of EG
so EF = FG = 5
EG = EF + FG = 5 + 5 = 10
</span>
EH = EF + FH = 5 + 11 = 16
answer
EH = 16
Answer:
18
Step-by-step explanation:
The pattern goes X2 then -3 interchangeably.
6 x 2 = 12
12 - 3 = 9
9 x 2 = 18
18 - 3 = 15
