Answer:
324 ft
Step-by-step explanation:
1. We know there are 3 points (A, B, and C)
so far. We also know B is in the middle of A and C.
A----B----C
2. Reading further, post B is 2x as far from C as it is from A.
A----B----.----C
3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).
A----B----.----C
<- 486ft ->
4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.
A----B----.----C
1 2 3
5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.
A----B----.----C
162 162 162
6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.
7. Make sure to put it into the correct form to answer (ft) and there you go!

Answer:
x = -2i and x = 2i
x = 3 and x = - 3
Step-by-step explanation:
x^4 - 5x^2 - 36 = 0
let u = x^2 and substitute
we have:
u^2 - 5u - 36 = 0
(u - 9)(u + 4) = 0
u = 9 and u = - 4
substitute back for u
x^2 = 9
x = 3 and x = - 3
x^2 = -4 -- i am going to assume you've learned imaginary numbers; otherwise, you cannot take the square root of a negative number.
x = -2i and x = 2i
