KFC. Keep change flip. Add instead of subtracting then there's your answer.
10% of 30 is 3, which means it rained 3 days.
30-3 = 27 days NO rain
3/30=9/v
3×3=9
30×3= 90
v=90
The result is
9
a
2
−
16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−
b
)
=
a
2
−
b
2
.
By applying this to our question, we obtain that:
(
3
a
−
4
)
⋅
(
3
a
+
4
)
=
(
3
