Answer: B and C
Step-by-step explanation:
404 + 50 + 50 = 504
you are buying 144 magazines total
504/144 = cost of one magazine
cost of one = 3.50
you are paying $60 a year for 12 years
60 x 12 = 720
720/144 = 5
5 - 3.50 = 1.50
2.
120x + 180x = 1080
300x = 1080
x = 1080/300
x = 3.6
3.6 x 60 = 216
Answer:
That x is any number bigger that 5 so 6 plus
Step-by-step explanation:
A) multiply equation A by -2 so you get -2x - 2z = -12 and then you can add both equations to eliminate z
Answer:
Take the square root of the constant (number w/o the variable) and then multiply that by 2.
Step-by-step explanation:
A perfect square trinomial is something like this:
If I have 6x, and I want to find the last term I would take half a six and then square it to get 9.
SO.... To get the middle term of a perfect square trinomial, you would need to do the reverse.. So...
1) Take the square root of the constant...
2) Multiply that by 2
The least common denominator is 1.
