Use u subsitution
the derivitive of eˣ+2 is eˣ
u=eˣ+2
du/dx=eˣ
du=eˣdx
we see a eˣdx in the problem
sub du for that and u for eˣ+2
remember
sub eˣ+2 for u
don't forget to add a constant since the derivitive of a constant is 0
the original function is
where C is a constant
I'm not sure about this one. I think its A
The answer is 4
5(1/5) + (1/5)(15)
Multiply
5/1 • 1/5 = 1
1/5 • 15/1 = 3
Add
3 + 1 = 4

Answer:
70 inches
Step-by-step explanation:
The pieces are in the ratio ...
shorter : longer = 1 : 3
so the shorter piece is 1/(1+3) = 1/4 of the total length. Its length is ...
(1/4)(280 in) = 70 in
