Picture 1:

6 + 8 = 14

Smaller Triangle Length - 2(14) - 2 = 26

Larger Triangle Length - 3(14) = 52

Length In Total - 78

x = 14

2nd Picture:

The scale is times 3

So the smaller image is 13 in length (13 * 3 = 39)

To make this possible: 23 - 10 = 13

x = 23

3rd Picture:

9 + 6 = 15

Larger Triangle: 2(15) + 4 = 34

Smaller Triangle: (15) + 4 = 19

Total Length - 53

x = 15

Hope This Helps!

8/(2x -2) = 14/(3x)

Cross multiply

24x = 28x - 28

Simplify. Isolate the x

24x (-28x) = 28x (-28x) - 28

24x - 28x = -28

-4x = -28

-4x/-4 = -28/-4

x = 6

-----------------------------------------------------------------------------------------------------------------

(x-10)/5 = 39/15

Cross multiply

15(x - 10) = 39(5)

Simplify

15x - 150 = 195

Isolate the x

15x - 150 (+150) = 195 (+150)

15x = 345

15x/15 = 345/15

x = 23

-----------------------------------------------------------------------------------------------------------------

(x + 4)/6 = (2x + 4)/9

Multiply 6 to both sides & 9 to both sides

9(x + 4) = 6(2x + 4)

Distribute 9 to x and 4, and 6 to 2x and 4

9x + 36 = 12x + 24

Isolate the x.

9x (-12x) + 36 (-36) = 12x (-12x) + 24 (-36)

9x - 12x = 24 - 36

-3x = -12

Isolate the x. divide -3 from both sides

-3x/-3 = -12/-3

x = -12/-3

x = 4

-----------------------------------------------------------------------------------------------------------------

hope this helps

Which statement best describes the roots of the polynomial function<br> (Function in picture)
Alina [70]

Answer:

Root at -4 with multiplicity of 2

Root at 2 with multiplicity of 1

Step-by-step explanation:

You don't actually need to factor this, you can just use Vieta's formulas and deduce the answer by looking at the options.

It states that the product of the roots is equal to the constant over the coefficient of the highest degree term; in this case, it is 16/1=16.

If you take the product of the roots of each answer, you get (from top to bottom) 16, 4, -16, and -4, which means that only the first answer is correct.

Help me on 23 please
ElenaW [278]
In this situation you would use cos 
which is adjacent over hypotenuse 
so I take the cos50 and have it equal to 17 / x
 cos(50)= 17/x 
which is the same as ...
17 divided by cos(50) =x 
x=26.44730506
which rounds to 26.45 
So your answer would be A)

I hope everything makes sense, enjoy! <span />
