Explanation:
_______________________________________________
(12a <span>+ 7b) + (−6a − 9) + (14a − 12b) =
12a </span><span>+ 7b + 1(−6a − 9) + 1(14a − 12b) =
</span>
12a + 7b + (1*-6a) + (1*-9) + (1*14a) + (1* -12b) =
12a + 7b − 6a − 9 + 14a − 12b = ?
Combine the "like terms:
12a − 6a + 14a = 20a ;
7b − 12b = - 5b ;
and then we have "-9" ;

So, write as: " 20a − 5b − 9 " ; which is: Answer choice: [A].

Answer:
3.99 inches
Step-by-step explanation:
<u><em>The correct question is</em></u>
The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.
What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth
we have
This is a exponential growth function
where
f(x) represent the length (in inches) of an image
x is the number of times the image is enlarged
so
For x=3
substitute in the exponential equation
