19 + 2[6-(6-4)2]
19 + 2[6 - 2*2] <--Parentheses first
19 + 2[6 - 4] <--- Multiply next in brackets
19 + 2[2]
19 + 4
23.
4(r - 20) + 3r
4(15 - 20) + 3(15)
4(-5) + 15
-20 + 15
-5.
Note that this a difference of squares:
where a = q and b = 1 (a^2 - b^2)
Therefore, our answer is q^2 - 1.
Por cada 1 a 3 puntos, como se cual usar?
Si 1 punto adicional --> 113 - 46 = 67 --> 67*100 = $6700 + $4200 = $10,900.
Si 2 puntos adicionales --> 113 - 46 = 67 --> 67/2 = 33.5 --> 33.5*100 = $3350 + $4200 = ....
Si 3 puntos adicionales --> 113 - 46 = 67 --> 67/3 = ........................

Necesitas usar el "2nd" key primero en la calculadora. Entonces, usas el "atan" key.
Tambien, puedes escribir atan(#) cuando # es un numero o otra cosa.
Are you trying to apply this to a function such as f(x) = x^2 + 1?
If we plug in x = 1 and x = -1, we obtain a value of 2 (two different inputs yielding the same output).
5.5 --> Note that if you multiply by 10, you get 55. To get back 5.5, you have to divide by 10.
So, 5.5 --> 55/10.
You can simplify this by dividing both the numerator and denominator by 5:
55/10 --> 11/2.
Multiply the numerator by 2 since 10*2 = 20 --> 3*2 = 6 --> 6/20.
130000*0.0057 = 741.
11.045
First, we can take out the 11 leaving 0.045.
Now, if you multiply 0.045 by 1000, you get 45...so 45/1000
Along with the 11, we have 11451000.
We can reduce this by dividing both the numerator and denominator of 45/1000 by 5.
119200.
