Draw circles counting each circle by two, or five if you want it to go faster.
Answer:
4(x +3)(x +4)
Step-by-step explanation:
First of all, recognize that each coefficient is a multiple of 4.
Factoring that out makes it easier to see that you need factors of 12 that add to give 7. Those are not hard to find as being 3 and 4. These numbers go into the binomial factors to give ...
... 4x^2 +28x +48 = 4(x^2 +7x +12) = 4(x +3)(x +4)
Answer: x1 = 10
x2 = 16
x3 = 28
Step-by-step explanation:
Not sure exactly what you mean, but heres the answers i got for this:
Exact form: 15/2
Decimal form: 7.5
1) Start with 4 and add 2 repeatedly
2) Start with 2 and multiply by 2 repeatedly
3) 15, 18, 21
