Completing the square follows the principle of taking
and converting it into
where d is the 'correctional number' as I like to call it - i.e. the number that converts the expanded bracket into the +c, since the expanded bracket will give us
.
In this case, 2/2=1 so we have the first part:
.
Expanding this gives us
. We need c to be 9, so we can just add 8.
Putting this together:
Now we can solve it more easily.
Rearranging:
1) order the numbers from smallest to largest
67, 76, 76, 82, 84, 87, 93
2) the middle number is the median as there are an odd number which makes it easier.
The median is 82.
Answer:
He will need to mow 5 lawns.
The equation that can be used to calculate the surface area of the triangular prism net shown below is mathematically given as
SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)
<h3>Which equation can be used to calculate the surface area of the triangular prism net shown?</h3>
Generally, The region or area that is occupied by the surface of any particular item is referred to as that object's surface area.
In conclusion, the equation surface area of the triangular prism will be one that accommodates all parameters
SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)
SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)
