Step-by-step explanation:
I can guess what the instructions are, but it'd be helpful if you were to share them.
3x^2 - 5x - 1 = 0 is a quadratic with coefficients {3, -5, -1}. Find the discriminant b^2 - 4ac: 25 - 4(3)(-1) = 13.
Because the discriminant is positive, we know we have two unequal real roots here. Continuing with the quadratic formula, we obtain:
-(-5) ±√13 5 ± √13
x = ----------------- = ----------------
2(3) 6
The first step is to find out what one centimeter of map represents. 15÷2.5 is equivalent to 6 kilometers. We now know that one centimeter is equal to 6 kilometers. Now we will have to multiply 17.5 by 6, which would equal 105.
Answer:
A
Step-by-step explanation:
For every additional goodie bag, you're adding the original number to itself and so on...
Example:
1 Goodie bag = Candy: 2 Toys: 3
2 Goodie bags = Candy: 4 Toys: 6
3 Goodie bag = Candy: 6 Toys: 9
So you would divide 89 by 3, and you should get 29.6
Your answer will be 0.
Because if 3+x is the same as x+3. That is literally the same as 3+0=3. You can plug the 0 into the variable
