It Is the number x2, then +1. so 30x2+1
Answer:
x=2
x=-5
Step-by-step explanation:
You need to get everything on one side to have a quadratic equation:
x^2+6x-4 -(3x+6) = x^2+3x-10
All factors of 10 are 1*10 and 2*5.
5-2 = 3 and 5*-2 = -10
Factoring x^2+3x-10 gives us (x-2)(x+5)
x=2
x=-5
Well, kid all you have to do is add like terms and place the subjected terms in alphabetical order.
1. (6y-2c+2)+(-3y+4c)
2. 6y + - 3y = 3y
3. -2c+4c =2c
4. the positive in the first set of parenthesis has to term other than its number by itself. (so it remains alone and only positive 2)
5. take all the separate term answers and add them into a complete expression- 3y + 2c + 2: and that is all
Answer: 2000
Step-by-step explanation:
Set up equation
The total signatures she needs is 4 times as many as she has. From this we can create the equation (4n = total signatures)
We know that the total number of signatures is 8000, so plug this into the equation to get 4n = 8000
Solve for n
Now that we have an equation, we can solve for n by dividing both sides by 4
4n = 8000
n = 8000 / 4 = 2000
Final Answer
Fiona has collected 2000 signatures so far
