<u>Answer:</u>

- 2 a + 7 b

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

5 a + 3 b - 7 a + 4 b

Re-arranging this expression by writing the like terms together to get:

5 a - 7 a + 3 b + 4 b

Now simplifying it by adding and subtracting the terms to get:

- 2 a + 7 b

<h2>>>Exponent</h2>

__________

\:

( \frac{1}{9} ) {}^{a + 1}  =  {27}^{2 - a}

( {3}^{ - 2} ) {}^{a + 1}  =  ( {3}^{3}  ) {}^{2 - a}

\cancel{ {3}}^{ - 2a - 2}  =   \cancel{{3}}^{6 - 3a}

-2a - 2 = 6 - 3a

-2a + 3a = 6 + 2

a = 8✔

Please fill in the missing blanks! I will give brainly to the best!
tigry1 [53]

The required missing terms are sequential as 3, -8, -10, 1, -9, -7, 5, 10, 6, -9, 1, -1, 1,  and -7.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
What we do is, lets fill the blank space be x,
Now for 1,
[-1] + [-1] + x = 1
-2 + x = 1
x = 1 + 2
x = 3
Similarly, all the blank spaces can be determined as, -8, -10, 1, -9, -7, 5, 10, 6, -9, 1, -1, 1,  and -7.

Thus, the required missing terms are sequential as 3, -8, -10, 1, -9, -7, 5, 10, 6, -9, 1, -1, 1,  and -7.
