Answer:
9
Step-by-step explanation:
To remove (-6) from the brackets, two minuses (negatives) cancel each other out becoming a plus (positive).
Example:
3 - (-6) = 3 + 6 = 9
*tip: if you see "- (-" imagine it automatically become a +*
The range for boys is 60 as for girls the range is 80. The median for boys is 90 and for girl 110.
We can let the radius of the semi circles be r and x can be the length of the rectangle.
The perimeter will be Perimeter = 2x + 2pr = 1200
The area of the rectangle is Area = x(2r)
Once we solve the perimeter equation, you get x = 600.
Put this into the area equation and you get Area = (600 - pr)(2r)
The maximum then gives r = 95. 493 and area 57, 295.8
Dimensions
Height is twice the radius or 190.986. Find base use equation x = 600 - p(95.493) = 300.
This means dimensions are 300 by 190.986
