Simplify ( 5 x 3-x+14)-(3 x 2-9 x + 4)= 5x3 - 3x2+8x+10
There are 10 cards and you are looking to find the probability of choosing 1 of 6 cards. so essentially 6/10 or 3/5 which are both equivalent to 60%
Answer: 7 Boxes
Step-by-step explanation:
There are 4 classrooms and 29 boxes of markers. So, you would divide 29 by 4 which is 7.25. Then, you need to round it because you don't have a quarter of a box. So, each classroom will get 7 boxes.
I hope that helps!
The quadratic formula is above.
You want each equation in standard form: ax^2 + bx + c = 0
I begin each problem by defining variables.
For instance 3. Is in standard form. X^2 -2x - 3 = 0. a = 1, b = -2, c = -3
Now use quadratic formula: x = [- b + or - sqrt(b^2 - 4ac)]\2a
