Answer:
the shares will be 10.284 and 13.712
Step-by-step explanation:
let the ratios be 3x and 4x
- 3x + 4x = 24
- 7x = 24
- x = 3.428
so the shares will be
Answer:
There are 5 faces, 5 vertices, and 8 edges, so all of that together is 18
subtract 9 from 118 then subtract 84.25 from that amount then add 95.
Each friend will have to pay rounded to the nearest thousandth 0.996 so each friend will pay about .99 cents.
Answer:
x = i, mult 2; x = -i, mult 2
Step-by-step explanation:
First let's make a substitution to make this easier to factor.
Let u² = x⁴ and
u = x²
Now we can rewrite the polynomial as
u² +2u + 1 = 0
This factors easily into
(u + 1)(u + 1) = 0
By the Zero Product Property, either
u + 1 = 0 or u + 1 = 0
Putting back the x²:
x² + 1 = 0 or x² + 1 = 0
For the first one, even though they are the same:
x² = -1 so
x = ±√-1
Since that is not "allowed", we make the replacement of -1 = i²:
x = ±√i² so
x = ±i
For the second one, we need not repeat the whole process, but we find 2 more identical roots:
x = ±i
That means that the factors are
(x + i)(x - i)(x + i)(x - i) = 0
x = i, multiplicity 2 and
x = -i, multiplicity 2
