Answer:
x^2 -12x+36
Step-by-step explanation:
x^2 – 12x
Take the coefficient of x
-12
Divide by 2
-12/2 = 6
Square it
6^2 = 36
We need to add 36 to make x^2 -12x a perfect square trinomial
x^2 -12x+36
Oh I get this.
So what you have to do is leave the same denominator and just count. Once a fraction has the same numerator and denominator that means it is a whole number.
Answer:
20
Step-by-step explanation:
There are 15 in 600. There would then be 2.5 for 100, but we round that to 3. There are 1 per every 40 in 200, so we have 19. We have 20 left, and could expect at least one, so it is 20. :)
