(3v - 4)(3v + 5)
They are not equivalent.
They are not equivalent.
(8 + 3v)(8 + 3v) or (8 + 3v)2
10 + 8v - 3v = 10 + 5v
the output of 7805 is 2v or 3v if we give the input as 2v or 3v.
They are not equivalent.
No, they are not.
93=3v /3=/3 21=v
-7-(3v-x+5)
-8-3v = 4v+48 -3v-4v = 48+8 -7v = 56 v = -8
