Answer:
15.7079
Step-by-step explanation:
Make an equation. 3x+2=20
Subtract 2 on both sides: 3x=18
Divide by 3 on both sides x=6
The number is 6 :)
Answer: About 90 something, I believe I'm sorry I'm a bit rusty in these math problems.
Answer:
sin

(
x
) ⋅ sin
2
(
x
) cos
2
(
x
) → sin
2 (
x
) tan 2
(

)
Step-by-step explanation:
Assuming tan = 2
(
x
)
−
sin
2
(
x

=
tan
2
(
x

sin

,
tart off by rewriting tan
2
(
x
) in to its sin
(
x
) and cos
(
x
) components.

cos

−
sin

Next find a common denominator
(LCD:

) cos
2
(
x
) ⋅ (

Combine in to a single fraction and factor out a
sin
2 (
x) . sin
2
(
x
) − sin
2
(
x
) cos
2
(
x
) cos
2
(
x
) → sin
2
(
x) ⋅ sin
2
(

)
cos
2
(

)
Finally just rewrite sin
2
(
x
) ⋅ sin
2
(
x
) cos
2
(
x
) → sin
2 (

Answer: 1.225 and 20.208333r.
Step-by-step explanation: divide 12.25 but 2 and 5 to figure out how much it is then do the same so it would look like this, $=2.25/ 2/5= 1.225 and then $12.25/3/2= 20.208333r.
