HELP ME PLZZZZZZZZZZZZZZZZZ

Answer:

A = 173.82

Step-by-step explanation:

[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]

a = 6

substitute 6 for a

A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]

solve:

A = 2 (1 + [tex]\sqrt{2}[/tex]) 36

A = 173.82

Answer:

Around 173.8 km (rounded to the nearest tenth of a km

Step-by-step explanation:

The area of an octagon can be found using the expression:

A=2(1+sqrt of 2)a^2

plug your side of 6 in to create the following equation:

A=2(1+sqrt of 2)(6^2)

Solve for A:

A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.

A=72+72sqrt of 2

plug that in a calculator and you get around 173.8 km

Answer:

By angle sum property,

56 + 92 = 148

180 - 148 = 32

linear pair

so ,  180 - 32

= 148

The answer is 3/4, i don't know why that's not a choice....

Step-by-step explanation:

Answer:

(0.5 , -1.5)

Step-by-step explanation:

intersection of their diagonals (E): right at the mid-point of segment AC or BD

A (5 , 0)  and C (-4 , -3): E (x , y)

x = (5 + -4 ) / 2 = 0.5

y = (0 + -3 ) / 2 = - 1.5

E ( 0.5 , - 1.5)

check with BD: x = (3 + -2) / 2 = 0.5        y = (-3 + 0) / 2 = - 1.5

Answer:

both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately

Answer:

That triangle is called a Scalene Triangle

Step-by-step explanation:

6x^2 + 2x - 15x - 5

2x(3x + 1) -5(3x + 1)

(2x -5)(3x + 1)

The linear inequality (B) y>4x-5 represents the given solution set graph.

So, the linear inequality that represents the graph:

Graph the inequation as follows:

Now, we can easily notice that graph 2 which is of equation (B) y>4x-5 matches the given graph.

Therefore, the linear inequality (B) y>4x-5 represents the given solution set graph.

Step-by-step explanation:

(-7+1)/(5-1)=-6/4= -3/2 is the slope

answer is C

Answer:

C

Step-by-step explanation:

The formula for slope is rise/run

Rise is the difference between the y coordinates

Run is the difference between the x coordinates

To find the rise and run:

ex.

(a, b), (c, d)

rise:

d-b

run:

c-a

Slope:

d-b/c-a

In this situation:

rise:

-7-(-1)

run:

5-1

Slope:

-7-(-1)/5-1

= -6/4

=-3/2

So the answer is C

Answer:

272 square inches

Step-by-step explanation:

Given

[tex]l = 8[/tex] --- length

[tex]w = 2[/tex] --- width

[tex]h = 12[/tex] ---- height

Required

Determine the total surface area (SA)

This is calculated using:

[tex]SA = 2 * (lw + wh + lh)[/tex]

[tex]SA = 2 * (8*2+2*12+8*12)[/tex]

[tex]SA = 2 * 136[/tex]

[tex]SA = 272[/tex]

The total surface area is 272 square inches

Answer:

x = 2.5

Step-by-step explanation:

4(x + 7) = 38

4x+28 = 38

4x = 10

x = 2.5

log(x) - log(6) = 2 log(4)

Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):

log(x / 6) = 2 log(4)

Rewrite the right side, using the property n log(a) = log(aⁿ ):

log(x / 6) = log(4²)

log(x / 6) = log(16)

Cancel the logarithms (i.e. take the exponential of both sides):

exp(log(x / 6)) = exp(log(16))

x / 6 = 16

Solve for x :

x = 6 × 16

x = 96
