Find all values x=4x

2 answers:

8 0

There is only one number that satisfies x=4x, meaning the a number quadrupled is the same number.

That number is 0.

I guess if you want to be technical, then the square root of any negative number would also work. The square root of a negative number doesn't exist, it is what is called an "imaginary number". So in a way an imaginary number would be the same as four times an imaginary number.

If you want to get deep, then there's another case that works. Infinity. Which is a greater value, one infinity or four infinities? They're the same thing because they both never end.

Continuation of the other six questions find the value of eggs and tangent

n200080 [17]

Answer:

Step-by-step explanation:

1) ?

I can't see what that one given angle is .. but it's that mystery angle subtracted from 180 give the angle BOA then you know that's an isosceles triangle again that the BOA is part of... so then just subtract BOA from 180 to find the two other angle of that triangle... they are the small so just divide your answer of 180-BOA /2 is the angle of each.. then since you know those to smaller angles subtract one from 90 to find the angle BAX

2) ( as we would read normally)

You're making this really tough on me.. I can just barely read the equations

I think it's 1+6x and 7x-3 . b/c they are the same length sides you can set those equal

1+6x = 7x -3

4+6x = 7x

4 = x

that worked out well :

for the tangent.. it's Tan(Ф)= Opp/ Adj

but I don't know which side they want to solve for.. I think you may have left off some of the instructions???? :/

ohh I think they really mean.. what's the length of the tangent lines .. that was confusing to me.. :/ just plug in 4 into x for either eq.

1+6(4) = 25

7(4)-3=25

tangent is 25

x-2 = 2x-10

x+8 = 2x

8 = x

again they made it work out easy :)

Then plug 8 into either equation to find the length of the tangent lines

8-2=10

tangent is 10

4) = 2) ??? they are the same question maybe you meant to put something else?
