Answer:

Step-by-step explanation:
Recall the form of the difference of squares.

Now let's apply it to your numbers:

Simplify:

Step-by-step explanation:
a = 1, b = 9, c = 8
with the quadratic formula;
x = -9 + \|9² - 4(1 × 8) ÷ 2(1) or x = -9 - \|9² - 4(1 × 8) ÷ 2(1)
x = -9 + \| 81 - 32 ÷ 2 or x = -9 - \| 81 - 32 ÷ 2
x = -9 + \| 49 ÷ 2 or x = -9 - \| 49 ÷ 2
x = -9 + 7 ÷ 2 or x = -9 - 7 ÷ 2
x = -2 ÷ 2 or x = -16 ÷ 2
x = -1 or x = -8

8 is your answer.
I hope this helps!
It will be 89 because 27+17+15+13+8+3+6
Using the formula, the distance between points (-3,2) and (7,13) is of 14.9 units.
<h3>What is the distance between two points?</h3>
Suppose that we have two points,
and
. The distance between them is given by:

This formula is derived from the Pythagorean Theorem, as the points form a right triangle in the xy-plane, with the hypotenuse being the distance between them.
For this problem, the coordinates of the points are given as follows:
(-3,2) and (7,13).
Hence we apply the formula to find the distance between them as follows:

The distance is of 14.9 units.
