Given the coordinates of two points, P1 and P2, the distance formula between these two points is deduced.
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
To find the area of the figure we must first find the area of the rectangle and add the area of the parallelogram.
rectangle area
A = (L) * (w)
L = root ((- 6-2) ^ 2 + (- 1-1) ^ 2) = 8.25
w = root ((- 6 - (- 5)) ^ 2 + (- 1 - (- 5)) ^ 2) = 4.12
A = (8.25) * (4.12) = 33.99
Parallelogram area
A = (b) * (h)
b = root ((3-3) ^ 2 + (3 - (- 3)) ^ 2) = 6
h = root ((3-2) ^ 2 + (3-3) ^ 2) = 1
A = (6) * (1) = 6
The total area is then
Atotal = 33.99 + 6 = 39.99 units ^ 2
Answer
the area of this figure is 39.99 units ^ 2
$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher
From the total $79 we substract the $29 she paid with cash or card.
79-29=50
So the value of the voucher is $50

Answer:
y = - 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 10 when x = 2, thus
k = 
= 
= - 5
y = - 5x ← equation of variation
Answer:
The average speed of the cyclist would be 14.5 km/hour.
Step-by-step explanation:
64/4=16
26\2=13
16+13=29
29/2=14.5
Answer:
Square all side lengths. If the longest side length squared is equal to the sum of the squares of the other two side lengths, Then it is a right triangle.
