The total will be 08.99 because that’s how you divide and he is winning
Check the picture below.
now, let's keep in mind that, the vertex is half-way between the focus point and the directrix, it's a "p" distance from each other.
since this horizontal parabola is opening to the left-hand-side, "p" is negative, notice in the picture, "p" is 2 units, and since it's negative, p = -2.
its vertex is half-way between those two guys, so that puts the vertex at (-5, 3)

Hey there!!
Let us take the first number as ' x '
According to the question
The second number exceeds the first number by 15
hence, the second number = x+15
The sum of both the numbers = 69
which means
x + x + 15 = 69
2x+15 = 69
Subtracting by 15 on both sides
2x + 15 - 15 = 69 - 15
2x = 54
dividing by 2 on both sides
x = 27
first number = 27
second number = 27 + 15
= 42
Hope my answer helps!
Answer:
First you need to convert 8 feet into inches, which is 96 inches
Next divide 96/6 to get 16.
Answer: You need 16 6inch fence slats
Step-by-step explanation:
To find the perimeter of irregular shapes in general, you just add the length of the sides.
To find the area of irregular shapes, first, draw a line to separate the two shapes, then find the area of those two shapes and add them up.
