Options are not shown but…
A square has 4 equal length sides and a right angle
Or two equal length diagonals which are perpendicular
Or 4 right angled corners and two adjacent sides equal
Or perpendicular diagonals with the same midpoint
Using the last one…
Gradient of AC = (5 - 3)/(-3 - 3) = 2/-6 = -1/3
Gradient of BD = (7 - 1)/(1 - -1) = 6/2 = 3
-1/3 x 3 = -1 so AC and BD are perpendicular
Midpoint of AC = ((-3 + 3)/2 , (5 + 3)/2) = (0, 4)
Midpoint of BD = ((1 + -1)/2 , (7 + 1)/2) = (0, 4)
QED
When rounding to the nearest hundredth, you must look to the thousandths place. since it is a 3, it rounds down, to **0.02**

Answer:
A). $(55 + 20w + p)
B). $180.50
Step-by-step explanation:
A). Fees to inspect a car = $55
Per hour charges for any work = $20
Therefore, charges of 'w' hours of work = $20w
Cost of parts = $p
Total cost of a repair job = $(55 + 20w + p)
B). If w = 2.5 hours and p = $75.50
From the expression,
Total cost of the work = $[55 + (20×2.5) + 75.50]
= $(55 + 50 + 75.50)
= $180.50
