9(3n + 8) = 180
3n + 8 = 180/9
3n + 8 = 20
3n = 20 - 8
3n = 12
n = 12/3
n = 4 <==

Identify an equation that models the situation and find its solution. Kane planned to build a 53-centimeter-tall model of a buil

alex41 [277]

Answer:

The increment in the model is 106cm

Step-by-step explanation:

Given

$Initial\ Height = 53cm$

$Final\ Height = 159cm$

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

$Increment = Final\ Height - Initial\ Height$

$Increment = 159cm - 53cm$

$Increment = 106cm$

<em>Hence, the increment in the model is 106cm</em>

12^13–12^12+12^11 is divisible by 7 and 19.

fiasKO [112]

Answer:

The statement is true

Step-by-step explanation:

The question is as following :

$12^{13}-12^{12}+12^{11}$ is divisible by 7 and 19, true or false?

The given expression is $12^{13}-12^{12}+12^{11}$

Take $12^{11}$ as a common

$12^{13}-12^{12}+12^{11} = 12^{11}*(12^2-12^1+12^0)\\= 12^{11} *(144-12+1)\\=12^{11} * 133\\= 12^{11} * 7 * 19$

So, $12^{11} * 7 * 19$ divided 7 = $12^{11} * 19$

And $12^{11} * 7 * 19$ divided 19 = $12^{11} * 7$

$12^{13}-12^{12}+12^{11}$ is divisible by 7 and 19 (<u>True</u>)
