Answer: 6 and 9, 7 and 8. 69, 78, 87, 96. So, there are only 4 combinations which would result in 15.
Step-by-step explanation:
Therefore the average sum of three numbers is 45:3=15. The number 15 is called the magic number of the 3x3 square. You can also achieve 15, if you add the middle number 5 three times. The odd numbers 1,3,7, and 9 occur twice in the reductions, the even numbers 2,4,6,8 three times and the number 5 once.
Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance= 
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ = (2-5)²+(4-(-3))²
PQ = (-3)²+7²
PQ= 9+49
PQ=58
So,the distance of PQ is
Answer
the slope intercept is y= -5/2x-6
hope this helps and have a wonderful day :)
There is no image posted. However, I will tell you how to solve for the area of a drum head.
Drum head is a circle shape. We will use the formula of finding the area of a circle to solve for the area of a drum head.
Area of a circle = π r²
π is pi. It is equivalent to 3.14. Though there are still a lot of numbers after 4. To ensure uniformity, π is 3.14
r is radius. It is the line from the center of the circle to the edge of a circle.
if the diameter of a circle is given, simply divide the diameter by 2 to get the radius.
Diameter is the line that starts from one end of the circle to the other passing through the midpoint of the circle.
Example:
The drum head has a diameter of 10. What is the area.
diameter is given, so we need to get the radius: 10 ÷ 2 = 5
Area = π r²
= 3.14 * 5²
= 3.14 * 25
Area = 78.50 square unit
Area is always in a square unit.
\left[x _{2}\right] = \left[ \left( \frac{1}{6}\,i \right) \,\sqrt{3}\,\sqrt{\left( -4+8\,y\right) }\right][x2]=[(61i)√3√(−4+8y)] totally answer
