Rewrite in simplest terms: <br> 10 ( 7 g − 9 h ) − 4 h − 8 ( − h + 8 g )

Ksju [112]

Answer:

$6g -86h$

Step-by-step explanation:

$10( 7g-9h) -4h - 8(-h + 8g)$

1) First, distribute the 10 and the -8 to the terms in the parentheses next to them. Remember, don't distribute to the -4h since it is not in the parentheses.

$10( 7g - 9h) -4h - 8(-h + 8g)\\70g - 90h-4h+8h-64g\\$

2) Next, combine like terms. (Any terms that have the same variables must be added together by their coefficients.)

$70g - 90h-4h+8h-64g\\\\70g-64g-90h-4h+8h\\6g-86h$

There are no more like terms to combine, so $6g -86h$ is the answer.

Given the sequence 8, 16, 32, 64, ..., which expression would give the thirteenth term?

mrs_skeptik [129]

8, 16, 32, 64,…
×2 ×2 ×2

$a_{n} = a_{1} * r^{n - 1}$
$a_{n} = 8 * 2^{13 - 1}$
$a_{n} = 8 * 2^{12}$
$a_{n} = 8 * 4096$
$a_{n} = 32768$

   First Term: 8
      Second Term: 16
      Third Term: 32
      Fourth Term: 64
       Fifth Term: 128
      Sixth Term: 256
   Seventh Term: 512
   Eighth Term: 1024
   Ninth Term: 2048
      Tenth Term: 4096
   Eleventh Term: 8192
   Twelfth Term: 16384
Thirteenth Term: 32768

$The\ expression\ that\ would\ give\ the\ thirteenth\ term\ of\ the\ problem\ would\ be\ the\ equation\ of\ the\ geometric\ sequence,\ which\ is\ equal\ to\ a_{n} = a_{1} * r^{n - 1}.$
