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:
2
Step-by-step explanation:
Because it goes into the positives and then comes out to be 2
Let x be the number.
Then the equation can be written as
3 -2x = x +8
The value of x after the simultaneous rotation and translation of pentagon A to create pentagon B is 110°
<h3>What is the translation of plane figures?</h3>
A plane figure translation is an isometry that translates each position of the figure at a distance and in a direction indicated by the vector.
It is also regarded as a sort of transformation that involves sliding each point in a plane figure at an identical distance in a similar direction.
From the attached image, the value of x after the simultaneous rotation and translation of pentagon A to create pentagon B is 110°.
