Answer:
8
Step-by-step explanation:
The coordinate pair (-4,5) could be the fourth vertex of the square.
<h3>Quadrilaterals</h3>
There are different types of quadrilaterals, for example: square, rectangle, rhombus and trapezoid. Each type is defined accordingly to its length of sides and angles. For example, the square has all side equals and angles equal to 90°.
For solving this question, you should plot the given points as shown in attached image. Note that you have only two sides of a square, and you need a point (W) for completing the square.
As you have a square, all sides should have the same dimensions and all angles should equal to 90°. Therefore, the coordinates for the point W should result in equal and parallel sides XY and XZ. For this, from the attached image, you can see that the x-coordinate for the point W should be equal to the x-coordinate for the point Z. And, the y-coordinate for the point W should be equal to the y-coordinate for the point Y.
Thus, coordinate pair (-4,5) would be the fourth vertex of the square.

The function is y = 3(x+3)^2-9
The equation of a parabola is
y=a(x-h)^2+k
where (h,k) are the coordinates of the vertex and a, is a constant.
From the question, we have
(h,k)=(-3,-9)
⇒y=a(x+3)^2-9
To find a, substitute x=-2,y=-6
-6=a(-2+3)^2-9
⇒a=3
The equation, y=3(x+3)^2-9
Multiplication:
Mathematicians use multiplication to calculate the product of two or more numbers. It is a fundamental operation in mathematics that is frequently utilized in everyday life. When we need to combine groups of similar sizes, we utilize multiplication. The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.

Answer:
-1/7=n
Step-by-step explanation:
We can use cross products to solve
5 7
-------- = ------
n+3 4
5*4 = 7*(n+3)
20 = 7*(n+3)
Distribute
20 = 7n+21
subtract 21 from each side
20-21 = 7n+21-21
-1 = 7n
Divide each side by 7
-1/7 = 7n/7
-1/7=n
