Should be double
answer is 4800
------------------------------
The numerator is like the divided and the denominator is like the divident.
Answer:
Lo mcm es 252.
Step-by-step explanation:
El objetivo de esta queston es encontrar el mínimo multiplo comun de estes tres numeros.
Para eso, factoramos estes numeros en valores primos, e despues multiplicamos estos factores.
12 21 63
12 - 21 - 63|2
6 - 21 - 63|2
3 - 21 - 63|3
1 - 7 - 21|3
1 - 7 - 7|7
1 - 1 - 1
2*2*3*3*7 = 252
Lo mcm es 252.
All of Sally's "likes" are squares: 225 = 15², 900 = 30², 144 = 12²
1600 = 40²
Sally "likes" 1600
Start by taking out a common factor.
x^10
x^10(x^6 - 2x^5 - x^4 + 4x^3 - x^2 - 2x + 1) = 0
So far we know that D won't work.
x - 1 is a factor because putting 1 in for the xs in the expression inside the brackets gives 0 Now you need to do a division. I'm going to assume you can do that.
Using division, I get
x^5 - x^4 - 2x^3 + 2x^2 + x - 1 Now divide x - 1 into this mess again. You get
x^4 - 2x^2 + 1 which factors into
(x^2 - 1)(x^2 - 1) which factors into
(x - 1)(x + 1)(x - 1)(x + 1) = 0
The first two divisions add (x -1)(x - 1)
========================
So we have (x - 1) with a multiplicity of 4 and (x + 1) with a multiplicity of 2
or x = 1 with a multiplicity of 4 and x = -1 with a multiplicity of 2 and x = 0
with a multiplicity of 10
That's the answer.
