Answer:

x=3

Step-by-step explanation:

Simplifying

2(6x + 9 + -3x) = 5x + 21

Reorder the terms:

2(9 + 6x + -3x) = 5x + 21

Combine like terms: 6x + -3x = 3x

2(9 + 3x) = 5x + 21

(9 * 2 + 3x * 2) = 5x + 21

(18 + 6x) = 5x + 21

Reorder the terms:

18 + 6x = 21 + 5x

Solving

18 + 6x = 21 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

18 + 6x + -5x = 21 + 5x + -5x

Combine like terms: 6x + -5x = 1x

18 + 1x = 21 + 5x + -5x

Combine like terms: 5x + -5x = 0

18 + 1x = 21 + 0

18 + 1x = 21

Add '-18' to each side of the equation.

18 + -18 + 1x = 21 + -18

Combine like terms: 18 + -18 = 0

0 + 1x = 21 + -18

1x = 21 + -18

Combine like terms: 21 + -18 = 3

1x = 3

Divide each side by '1'.

x = 3

Answer:

x=3

Step-by-step explanation:

(12x+18-6x)=5x+21

6x+18=5x+21

x+18=21

x=3

Answer:

Zero

Step-by-step explanation:

The line is a straight line going across the x axis so there is no change in y so there is no slope because slope is the change of y.

Answer:

x = 9

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve:

[tex]a^2+b^2=c^2[/tex]

→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:

[tex]40^2+b^2=41^2[/tex]

[tex]1600+b^2 = 1681[/tex]

→Subtract 1600 from both sides:

[tex]b^2=81[/tex]

→To get "b," by itself, square root both sides, like so:

[tex]\sqrt{b^2} =\sqrt{81}[/tex]

→81 is a perfect square meaning it has two factors that are identical.

[tex]b = 9[/tex]

Answer:

C 720`

Step-by-step explanation:

The sum of the interior angles of the hexagon is S = 720°

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the sum of the interior angles of a hexagon be S

Let the polygon be represented as a hexagon

Now , the number of sides of a hexagon is n = 6

So , sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

On simplifying , we get

nθ = S = 180 ( 6 - 2 )

S = 180 x 4

S = 720°

Therefore , the value of S is 720°

Hence , the sum of the interior angles of hexagon is 720°

Answer:

THE FUNCTION IS ALWAYS INCREASING.

Complete question: The graph of f(x)= power of 3√x + 8 is shown.

Step-by-step explanation:

See attachment for the missing graph.

when x = -16 ; y = -2

when x = -12 ; y = -1.5

when x = -8 ; y = 0

when x = -6 ; y = 1.25

when x = 0 ; y = 2

when x = 6 ; y = 2.5

As the value of x increases, so does the value of y. Thus, the function is always increasing.

this is because you can slip the triangle into two different triangles and then find both their areas and combine them

Answer:

Step-by-step explanation:

let base be x and height be 3x

we know area of parallelogram is

base*height

ie x*3x=675

3x^2=675

x^2=675/3

x^2=225

x= square root of 225

x=15

therefore base =15

height = 45

Answer:

I think it's TRUE

Since they're congruent triangles according to the given.

Answer:

The numbers are 72 and 96.

Step-by-step explanation:

LCM + GCF = 312

LCM - GCF = 264

2*LCM = 576

LCM = 576/2 = 288

HCF = 312–288 = 24

The product of two numbers = HCF*LCM

Let the numbers be x and (168-x)

x(168-x) = 24*288 = 6912

x^2–168x+6912 = 0

x = [168 +(168^2 -4*6912)^0.5]/2

= [168 +(28224–27648)^0.5]/2

= [168 + 576^0.5]/2

= (168+24}/2

= 192/2

= 96 and the other number is 168–96 = 72.

The coordinates of D'E'F' after reflection are,

D' = (0, - 3)

E' = (1, 0)

F' = (2, - 1)

We have to given that,

Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1).

Here, Triangle DEF is reflected across the y-axis.

The rule for a reflection over the y -axis is,

(x, y) → (- x, y)

Hence, the coordinates of D'E'F' after reflection is,

D' = (0, - 3)

E' = (- (- 1), 0) = (1, 0)

F' = (- (- 2), (- 1)) = (2, - 1)

Answer:

C!

Step-by-step explanation:

It appears that all choices have the 1st part the same, so we are looking at domains. I recommend drawing the functions without the domain limitations. We know that the linear function is closed so it's inequality is either [tex]\geq[/tex] or [tex]\leq[/tex]. So eliminate B and D. Since the quadratic function continues to the left the inequality sign should be <. So the answer is C

Step-by-step explanation:

Let's see. There is a missing side. Let's call that x. However, we know what the other sides are!

This is how we do it.

We know the largest side's length., 172.

Since we know the other sides, we can subtract their length from 172.

172-57-51-31=33

x=33

So now add the sides!
