NARA [144]

ANSWER

Step 3

EXPLANATION

The given polynomial expression is:

2 {p}^{2}  - 3p - 7 - (3 {p}^{2}  + p - 5)

Fatau correctly expanded the parenthesis in the first step.

2 {p}^{2}  - 3p - 7 - 3 {p}^{2}   -  p  +  5

Fatau also correctly grouped the like terms to obtain:

(2- 3) {p}^{2}   + (- 3 - 1)p  + (- 7 +  5)

Fatau committed a mistake at the third step.

Instead of obtaining,

- {p}^{2} - 4p   - 2

He mistakenly got:

{p}^{2}    - 2p  +2

The differences between the given locations ovtained by taking the absolute value of the difference between two points:

  • A and B = 202.25 meters
  • B and C = 1686.6 meters
  • C and D = 474.875 meters

The question involves calculating the difference in the distance between two points.

Location A = - 895.9 m

Location B = - 1098 3/20 = - 1098.15 m

Location C = - 2784.75

Location D = - 3259 5/8 = - 3259.625

Difference between Location A and B

  • |-895.9 - (-1098.15)| = 202.25 meters

Difference between Location B and Location C

  • |-1098.15 - (-2784.75)| = 1686.6 meters

Difference between Location C and Location D

  • |-2784.75 - (-3259.625)| = 474.875 meters

The differences between the different locations are :

  • A and B = 202.25 meters
  • B and C = 1686.6 meters
