4.5x5=22.5
not sure if this is right, but hope it helps
Answer:
From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.
Step-by-step explanation:
Here, the initial value = 2.5 y
The final value of 1.5 y
Now,as Final Value < Initial Value
So, there is a DECREASE IN THE VALUE.
Now, decrease in the value = Initial value - Final Value
= 2.5 y = 1.5 y = 1 y
or, there is a decrease of ( 1 y) in the given value.
Now, Percentage decrease in the value is given as:
![\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y} \times 100 = 40](https://tex.z-dn.net/?f=%5Ctextrm%7BPercentage%20Decrease%7D%20%3D%20%5Cfrac%7B%5Ctextrm%7BThe%20decrease%20in%20the%20value%7D%7D%7B%5Ctextrm%7BThe%20initial%20Value%7D%7D%20%5Ctimes%20100%5C%5C%20%3D%20%5Cfrac%7B1%20y%7D%7B2.5%20y%7D%20%20%5Ctimes%20100%20%3D%2040)
or, Percentage Decrease = 40%
Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
They are all quadrilaterals <span />
The answer is -(5x+16/x^2-22)
