Rewritten:
15w^9 - 10w^7 + 12w - 7
Leading coefficient: 15
Degree of the polynomial: 9
always because the opposite of a positive is a negative, and the opposite of a positive is a negative. But zero is neither positive or negative, therefore is has no real opposite and is zero.
In this exercise we have to use the knowledge of geometric progression to find three specific numbers, in this way we can say that these numbers correspond to;
Then using the formula of the geometric progression we find that:
now, the differences between the terms must be the same:
and now, when we increase the third term by 9,so we have:
Now we use that identity in the first equation :
The general solution for a quadratic equation is
We have that:
so, put the numbers in the formula we find:

Answer:
perimeter = 6w + 5 units
Explanation:
Perimeter of a rectangle can be calculated as follows:
Perimeter = 2(width + length)
We are given that:
width = w units
length is 5/2 units greater than twice the width. This means that:
length = 2w + 5/2
Now, substitute in the above equation to get the expression for the perimeter as follows:
Perimeter = 2(width + length)
Perimeter = 2(w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 2(3w) + 2(5/2)
Perimeter = 6w + 5
Hope this helps :)
where you write down a number this way:
In this example, 5326.6 is written as <span>5.3266 × 103</span>,
because 5326.6 = 5.3266 × 1000 = 5.3266 × 103
