Answer:

Step-by-step explanation:

Additive inverse of (5a² - 4a + 3) should be added to make them zero

(5a² - 4a + 3) + (-5a² + 4a - 3)=   <u>5a² - 5a² </u>  <u>- 4a + 4a</u>    <u>+ 3  - 3</u>

                                              = 0

Answer/Step-by-step explanation:

Given:

86.32947

Let's find the place value of each digit

8 => tens which is 80

6 => unit which is 6

3 => tenth which is 0.3

2 => hundredth which is 0.02

9 => thousandth which is 0.009

4 => ten-thousandths which is 0.0004

7 => hundred-thousandth which is 0.00007

If you add all of the it will give you 86.32947

Thus:

1. 6 => b

2. 8 => g

3. 4 => e

4. 7 => d (there's a mistake in the number of zeros written.)

5. 9 => c
