<span>There is a decrease of 20% from ÂŁ800 to ÂŁ640.
A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :
Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)
800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.</span>
20, 10 line segments each with 2 ends = 20
I hope this helps you
Perimeter =2 (width +length )
324=2 (67+length )
162-67=length
length =95
The answer should be h(3)= -5
