it equals 70
x=6
6
6 + m = 16 m = 16 - 6 = 10
-2
b = 6
144 9+7 = 16 and 9*16 = 144
Do you mean 1400v + 2v^7 (is 2v to the power 7)? When you differentiate, e.g. 2v^7, you bring the 7 to the front and reduce the power by 1. If so the answer is 1400 + 7*2v^6 (where * means multiply) or 1400 + 14v^6
16
Nope ! 24 is. 6 x 4 equals 24 ! Regarding 16, it is 6 x 2 equals 12, plus 4 is 16 !
144 9+7 = 16 and 9*16 = 144
Twelve plus four equals Sixteen12 + 4= 16
