Oooops..... read that backwards.......I'll be back shortly

Angle BED is 18+5x

Angle DEA is 162-5x

Angle CEB is 162-5x

Angle CEB = Angle DEA

Angle BED = Angle CEA

There are \(9\) members who are not Fred, so we can simply do ₉C₃ which equals \(84\).

AEC    and    BED    are equal (opposite angles)       BED = 18 + 5x

Angles AED and BEC are also equal opposite angles   and    added to the angle next to them (18+5x) equal 180

So   AED = BEC          AED +18+5x=180     AED = 162-5x = BEC

There is not enough information but I can tell you the maximum number on the shelf that could be sodium free.

This would be correct if ALL the cans on the shelf are vegetarian.

720-170-40 = 500

How do i solve this?

\(2a^2 + 4a - 48 \\ 2(a^2 + 2a - 24) \\ 2(a-4)(a+6)\)

let that expression equal x, then

\(\sqrt{12+x}=x \\ 12 + x = x^2 \\ x^2 -x -12 = 0 \\ (x-4)(x+3) = 0 \\ x = 4,~-3 \\ \text{however as x is a square root x > 0, thus }x=4\)

Rom has given you a hint, he has not answered your question as you should be able to take his hint and answer the question yourself.

I'll give you some more hints.

What is the gradient of     5x+8y=-9     ?

You may need to rearrange it and put it in the form     y=mx+b   where m is the gradient and b is the y intercept.

There are other ways to do it but this is the one most taught.

Then follow Roms hint.     i.e   The gradient of the other line is the negative recoprocal of the one you have.

If you cannot at least find the gradient of the line then you are not ready to answer this question.

And we are here to help you learn not to supply you with a cheat answer.

There are only 5    5 digit palindromes in base 2. They are

10001 base 2 which equals   17 base 10

10101  base 2 which equals   21 base 10

11011  base 2 which equals    27  base 10

11111  base 2 which equals     31  base 10

Which of these can be expressed as a palindrome in any base?   Let the base be x

which is of the form   ax^2+bx+a   (base 10)

                 where    a b and x are all  integers 

                 and a and b are both smaller than x

x=2 is too small

x=3, a=2       9a+b+a  =   10a+b  = 20+1  works        212 (base3) = 10101 (base2) = 21 (base 10)

So the question becomes... can I make 17 with a 3 digit palindrome.

101 base 4     That is obvious I should have seen it in the first place

\(10001_2=17_{10}=101_4\)

So the answer is  10001

they are perpendicular and what is m+b

The answer is 10001 in base 2, since it is equilvalent to 101 in base 4.

How is 10 a FIVE digit palindrome in base 2? It is 1010 in base 2, and not even a palindrome.

Yea that might be a better plan but if they are rescued soon then maybe Gilligan will be enough. 

Actually i'd chose one of the others. Maybe Thursten Howell III  or his wife?

Then again there are plenty of coconuts in those cocnut palms and also plenty of fish in the sea so maybe it is better that they don't eat anyone.   

For those who don't know what we are talking about. I know it is before most people's time :)

The key here is that if two lines, l1 and l2, with slopes, m1 and m2, are perpendicular then

m2 = -1/m1

1) is correct

2) don't guess

(-3 - i) + (5+6i) = (-3+5) + (-1+6)i = 2+5i

3) your guesses.... are not good

(8-3i)-(6+i) = (8-6) + (-3-1)i = 2 - 4i

-i is correct though it would be better if you understood why.

\(\forall n \in \mathbb{Z} \\ i^{4n} = 1 \\ i^{4n+1}=i \\ i^{4n+2}=-1 \\ i^{4n+3}=-i\)

for the first problem we have

\(2\sqrt{-27} = 2\sqrt{27}\sqrt{-1} = 6\sqrt3 i = 6i \sqrt{3}\)

the 3rd choice

you got the second one right but the first one is -2-8i

I dont know the first one but the second one is just -i

you are right with number 1 and 3 but the second one is just 4

170 mod 22 = 16th apartment, which is P.

The answer is x=2
