Hello,
(u*v)'=u'v+uv'
u=2x²+3 ==> u'=4x
v=sin 5x ==>v'=cos 5x *5
((2x²+3 sin (5x))'=4x* sin (5x) +(2x²+3)*cos (5x) * 5
Answer:
a because I dont know why but some one told me it was this
Wheres the picture of the model
hi
f(a+7)
f(x) =x²+5
by remplacing X by (a+7) :
then f(a+7) = (a+7)²+5
= a² +2*a*7 +49 +5
= a² +14a +54
There are 24 more yellow candies than green. 480 x .20 = 96, while 480 x .15 = 72. 96-72 = 24
