4,080,499 rounded to the nearest thousand is 4,080,000.
Answer:
31 terms.
Step-by-step explanation:
218 = 8 + (n-1)7
210 = (n-1)7
30 + n-1
n = 31
There would be 31 terms in the given AP.
Answer:difference of two squares will be
16y^2 -x^2 = (4y -x)(4y +x)
so the second choice
Step-by-step explanation:

Explanation:
1. The general form of a quadratic in standard form* is ...

An example is ...

The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.
__
2. The general form of a quadratic in vertex form can be written as ...

An example is ...

The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.
_____
* In the UK, "standard form" is vertex form.
