A) 2x + 11
B) 2x + 13
not sure because you put ?
D) 2x + 21
these are the answers to your answer options but the answer to the equation in the question is 2x + 13 so your answer is B! hope this helped
Answer:
Step-by-step explanation:
we will solve this using integration by parts as the problem is a product of two functions which none of them are constants.
∫udv = uv -∫vdu ..............equ 1
∫
u=x ,
du= 1
dv =
v=∫dv=
Substituting into equ 1
∫udv = - ∫
<em>∫udv = 
</em>
8 / 86 = 12 / x
cross multiply
(8)(x) = (86)(12)
8x = 1032
x = 1032/8
x = 129 pieces
His speed would be 2 km/hr.
Where S is speed, D is distance, and T is time, the equation "S=D/T" can be applied. You would substitute the information provided in this equation. However, since the time is in minutes but your answer must be in km per HOUR, you must convert it.
S=D/T
There is 60 minutes in an hour, so you would substitute 5/60 for T.
S=600km/5/60
S=2km/hr
