Multiply out the brackets first.
So 2(-4y-9)-5y becomes -8y-18-5y [2 times -4y and 2 times -9]
Then simplify -8y-5y-18 to the answer ......-13y-18 or -(13y+18)
Answer:
A 50% increase
Step-by-step explanation:
Area = length x breadth
Let illustrate this with an example
original dimensions
length = 4
breadth = 5
area = 4 x 5 = 20
new dimensions
length = 4/2 = 2
breadth = 5 x 3 = 15
area = 15 x 2 = 30
Percentage change = 30 - 20 / 20 x 100 = 50%
