Answer:
4
Step-by-step explanation:
p=120 -5Q
when p = 80
80 = 120 -5Q
Q=8
and when p= 60
60 = 120 -5Q
Q=12
so, change in consumer surplus = 12-8
= 4
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0
SOLUTION
Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²
In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70
The mule can carry approximately 3 wooden posts.
Because we know that a mule can carry ≈13kgs and each pole is 4.5 kg, so we do:
13/4.5≈ 2.88888889...≈ 3 wooden posts.
