I think it’s y=2 bu I’m not fully sure
20% is 0.2, so it is greater.
5. We need to subtract 20% from the selling price of 18 000 as that will give his cost price
20/100 X 18 000 = 3600
18 000 - 3600

1) Perfect squares:
a²+14a+49 = (a+7)²
a²+26a+169 =(a+13)²
2) Differences of squares
a²-36 = (a-6)(a+6)
w²-121 = (w-11)(ww+11)
