Answer:
Simplifying
(n + 9) + -1(2 + -2n) = 0
Reorder the terms:
(9 + n) + -1(2 + -2n) = 0
Remove parenthesis around (9 + n)
9 + n + -1(2 + -2n) = 0
9 + n + (2 * -1 + -2n * -1) = 0
9 + n + (-2 + 2n) = 0
Reorder the terms:
9 + -2 + n + 2n = 0
Combine like terms: 9 + -2 = 7
7 + n + 2n = 0
Combine like terms: n + 2n = 3n
7 + 3n = 0
Solving
7 + 3n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3n = 0 + -7
Combine like terms: 7 + -7 = 0
0 + 3n = 0 + -7
3n = 0 + -7
Combine like terms: 0 + -7 = -7
3n = -7
Divide each side by '3'.
n = -2.333333333
Simplifying
n = -2.333333333

Answer:
If the segments AU and UT are equal then AT equals 66, if the segments are not equal then AT equals 6x+24. Depends on what you are learning. Use what you need!
Step-by-step explanation:
4x+5 = 2x+19
2x=14
x=7
4(7)+5+2(7)+19 = 42+24 = 66
Answer:
The correct option is
Option d. Sin θ = -√65/9 and Tan θ = -√65/4
Step-by-step explanation:
Points to remeber
Sin θ = Opposit side/ Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ= Opposite side /Adjacent side
<u>To find opposite side</u>
It is given that,
Cos θ = -4/9 = Adjacent side/Hypotenuse
We can find opposite side of angle θ
opposit side ² = Hypotenuse² - adjacent side² = 9² - 4²
= 81 - 16 = 65
Opposite side = √65
<u>To find sinθ and tanθ</u>
Sin θ = Opposit side/ Hypotenuse = -√65/9
Tan θ = Opposite side /Adjacent side = -√65/4
Therefore the correct option is
Option d. Sin θ = -√65/9 and Tan θ = -√65/4

Answer:
the answer is 12
Step-by-step explanation:
p(n)= 6-2(1+n)
so if p(2)
then n=2
therefore,
p(2)= 6-2(1+2)
= 4×3
=12
