The obvious answer is 6. If three of the lengths are 6, and there are four total sides, then you would need 6 to complete the shape, as it is a square, and a square is a type of trapezoid.

If √6 is the geometric mean between 4 and another number, then the number is<br> 1.5<br> 9<br> 24
konstantin123 [22]
Correct answer is A.

g - geometric mean
g= \sqrt{ab} &#10;\\&#10;\\g= \sqrt{6} ,a=4,b=?&#10;\\ \sqrt{6}= \sqrt{4b} &#10;\\  (\sqrt{6})^2= (\sqrt{4b} )^2&#10;\\6=4b&#10;\\&#10;\\b= \frac{6}{4} = \frac{3}{2}=1.5

2x+2y=8 in function form step by step please?
nasty-shy [4]
You could get two different functions out of this:

<u>2x + 2y = 8</u>

1). <u> 'y' as a function of 'x'</u>

Subtract  2x  from each side:  2y  = -2x + 8

Divide each side by  2 :         <em> y  =  -x + 4</em>


2). <u> 'x' as a function of 'y' :</u>

Subtract  2y  from each side:    2x  =  -2y + 8

Divide each side by  2 :        <em>  x  =  -y + 4</em>

Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical.  In general, they're
not the same function.

I need help with this question about similar triangles
Colt1911 [192]

Answer:

ST = 12 units

Step-by-step explanation:

Δ RAS and Δ TES are similar triangles, thus the ratios of corresponding sides are equal, that is, noting that SR = 21 - ST, thus

\frac{ST}{SR} = \frac{TE}{AR} substitute values

\frac{ST}{21-ST} = \frac{8}{6} ( cross- multiply )

6ST = 8(21 - ST)

6ST = 168 - 8ST ( add 8ST to both sides )

14ST = 168 ( divide both sides by 14 )

ST = 12
