First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x

Explanation:
Factorizing your equation we get
cot
(
x
)
=
0
so
cos
(
x
)
=
0
we get the following Solutions in the given interval
x
=
π
72
or
x
=
3
π
2
for the second case we get
cot
(
x
)
=
−
1
so
cos
(
x
)
=
−
sin
(
x
)
and we get
x
=
3
π
4
or
x
=
7
π
4
Hint:
To get the Solutions of the last equation you can use
√
sin
(
x
+
π
4
)
=
0

Answer:
19
Step-by-step explanation:
sum means answer to an addition problem, so 41 - 22 = 19, so 22 + 19 = 41
Answer:
2,2
Step-by-step explanation:
f(x)=(x-2)^2+2
=2,2
