Answer:
x = 3
Step-by-step explanation:
Since the angle at the vertex is bisected then the following ratio is true
=
, that is
=
( cross- multiply )
4(9x - 9) = 3(6x + 6) ← distribute parenthesis on both sides
36x - 36 = 18x + 18 ( subtract 18x from both sides )
18x - 36 = 18 ( add 36 to both sides )
18x = 54 ( divide both sides by 18 )
x = 3
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>
