The pair of parenthesis that can be removed without changing the value of the expression is "parenthesis around 5 × 8"
Given expression:
(1 + 2) × (6 - 3) + (5 × 8) + (9 - 4)
Using BODMAS
(1 + 2) × (6 - 3) + (5 × 8) + (9 - 4)
= 3 × (3) + 40 + 5
= 9 + 40 + 5
= 54
Remove parenthesis around 5 × 8
(1 + 2) × (6 - 3) + 5 × 8 + (9 - 4)
By removing the parenthesis around 5 × 8, you still have to multiply before adding according to the rule of BODMAS
Therefore, the pair of parenthesis that can be removed without changing the value of the expression is "parenthesis around 5 × 8"

The unit rate of 600 miles in 7 hours is 85.71 miles per hour.
Given that, distance= 600 miles and time= 7 hours.
Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Here unit rate is
Speed =Distance/Time
= 600/7
= 85.71 miles per hour
Therefore, the unit rate of 600 miles in 7 hours is 85.71 miles per hour.
