n = 27

Answer:

n = 27

Step-by-step explanation:

(2n + n)÷9 = 9

multiply both side by 9

(2n + n) = 81

3n = 81

Divide both sides by 3

3n/3 = 81/3

n = 27

Answer:

-7/19

Step-by-step explanation:

Answer:b

Step-by-step explanation:

The area of the quadrilateral with the given coordinates is 27 square units.

The coordinates of the quadrilateral are A(0, 4), B(5, 2), C(3, -3) and D(-2, -1).

We need to find the area of the quadrilateral with the given coordinates.

The formula to find the area of the quadrilateral with coordinates ( x₀, y₀ ), ( x₁, y₁ ), ( x₂, y₂ ), ( x₃, y₃ ) is (1/2) × ( x₀y₁ - x₁y₀ + x₁y₂ - x₂y₁ + x₂y₃ - x₃y₂ + x₃y₀ - x₀y₃ ).

Now, Area=1/2×(0×2-5×4+5×(-3)-3×2+3×(-1)-(-2)×(-3)+(-2)×4-0×(-1))

=1/2×|(-20-15-6-3-6-8)|=27 square units.

Therefore, the area of the quadrilateral with the given coordinates is 27 square units.

Answer:

230[tex]cm^{2}[/tex]

Step-by-step explanation:

17*10=170

12*10*1/2=60

170+60=230

Step-by-step explanation:

if AD =17,then Dc is also 17 because from the diagram,it is given that AD=DC.

And because AD and DC are equal,it means AC = AD +DC,therefore AC = 17+17,AC =34

AC=2y-6

therefore

34=2y-6

28=2y and y=14

Answer C

f(x) = 4x

g(x) =

[tex] \sqrt{x^{2} \: - \: 1 } [/tex]

h(x) =

[tex] \sqrt{16x \: - \: 1} [/tex]

We want to check if h(x) = g(f(x))

So g(f(x)) =

[tex] \sqrt{(4x) {}^{2} - \: 1} [/tex]

Simplified;

g(f(x)) =

[tex] \sqrt{16x {}^{2} \: - \: 1 } [/tex]

But h(x) =

[tex] \sqrt{16x \: - \: 1} [/tex]

Hence g(f(x)) is not equal to h(x)

Answer:

0.006 is the larger decimal

Answer:

r = 9

Step-by-step explanation:

These are vertical angles, therefore, the measurements is the same. Set the two measurements equal to each other:

7r - 5 = 6r + 4

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 5 and subtract 6r from both sides of the equation:

7r (-6r) - 5 (+5) = 6r (-6r) + 4 (+5)

7r - 6r = 4 + 5

Simplify:

7r - 6r = 4 + 5

r = 9

9 is your value for r.
