So 5 1/2ft is 5.50ft u have 5.35ft so 5 4/10 is 5.40ft and u have 5.5ft so the shortest one is 5.35ft
-1/5 is -.2 and -2/3 is -.66  repeated and u have 2 and u have .4 so it would be
-2/3,-1/5,0.4,2 is ure answer

What is the value of x?
Elanso [62]
Since all the angles are congruent, the sides must be congruent too.


So, just have one equation on one side equal to another.

5x= 3x+6

Subtract 3x from both sides.

2x=6

Divide 2 into both sides.

x=3.

We can check this by seeing if all the sides are the same.

5(3)= 15

6(3)-5= 15

3(3)+6= 15

I hope this helps!

X^2 - 10x + 8 =0
x^2 - 10 + (-10/2)^2 - (-10/2)^2 + 8 = 0
(x - 5)^2 - 25 + 8 = 0
(x - 5)^2 - 17 = 0
To be honest , this is the final step for this equation. It seems like there is no any suitable answer for this question..
To me , I think the best answer will be the third option.
x - 5 =0
x = 5

2x-10 = 0
2x = 10
x = 5
I guess this answer seems like legit.. So I will choose the third option.

The inverse, f'(x), of f(x) =
astraxan [27]

Step-by-step explanation:

Given

f(x) =  \frac{x + 5}{x}

So

f(2) = \frac{2 + 5}{2}  \\  =  \frac{7}{2}

Now

{f}^{ - 1} (x) =  \frac{5}{x - 1}

So

{f}^{ - 1} (2) =  \frac{5}{2 - 1} \\  =  \frac{5}{ 1}   \\  = 5

Hope it will help :)❤
