1/4 is equivalent to 5/20
F(x) = 3 - x
f(-4) = 3 - (-4) = 7
answer
A. 7
Parameter is sum of all sides therefore
<span>2x + x + x + 13 = 125
4x = 125-13
4x = 112
x = 28</span>
The amount after the reduction of 15% for 100 = 85
<span>the amount after the reduction of 15% for 150 = (85/100) * 150</span>
= 127.5
