The type of quadrilateral is rectangle.
What is distance formula?
The distance between coordinate P(x1 , y1) and coordinate Q(x2 , y2) is calculated using the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]
Given coordinates: a(1, -1), b(0, 3), c(5, 5), and d(6, 1).
ab= √(0-1)² + (3+1)²
ab= √17
bc= √(5-0)² + (5-3)²
bc= √29
cd= √(6-5)² + (1-5)²
cd= √17
da=√(6-1)² + (1+1)²
da= √29
ac=√(5-1)² + (5+1)²
ac= √16+36
ac= √52
bd =√(6-0)² + (1-3)²
bd= √36+4
bd= √40

Answer:
true
Step-by-step explanation:
So
Total cost of the workbooks is d
And the number of workbooks is t
Therefore d = 95
95=19t
t=95/19=5
5 workbooks
The first one should be 7/26
