Answer:

2. 8³ - 14 × 6² - 2

4. |-6|

5. 7² - 3.1 - 19 × 2.1

Explanation:

To find the expressions, find the solution of the given equation, then solve for each answer choice to see if the soultions match. If they do, then the expressions are equivalent.

2² - 3³ + 29

4 - 27 + 29 = 6

6 is the value were looking for.

1. (78 ÷ 3) -
2^(4)

(78 ÷ 3) - 16

26 - 16

= 10

not equal

2. 8³ - 14 × 6² - 2

512 - 14 × 36 - 2

512 - 504 - 2

= 6

equal

3. -|-6|

= -6

not equal

4. |-6|

= 6

equal

5. 7² - 3.1 - 19 · 2.1

49 - 3.1 - 19 · 2.1

49 - 3.1 - 39.9

45.9 - 39.9

= 6

equal

Hence, choices 2, 4, and 5 have a value of 2² - 3³ + 29.

hope this helps!
