Answer:
A and C
Step-by-step explanation:
Using the fact that = i , then
=
= ×
= ± 4 × i
= 4i → A
= - 4i → C
the image is formed of a rectangle and a square
perimeter of the cabin = perimeter of rectangle + perimeter of square
= 2(l+b) + 4×side
= 2(7+5) + 4×5
= 24 + 20
perimeter of the cabin = 44 cm
We let x = Kim's amount
y = Laura's amount
z = Molly's amount
We have three unknowns and it should be that we have three equations to set up to be able to solve this.
x + y + z = 385 (1)
z - x = 105 (2)
2/5 = x/z (3)
Solving simultaneously, we can get the values as follows:
x = 70
z = 175
y = 140
Therefore, the percentage that Laura got was 36.4% of the whole money. Hope this answers the question.
