let nwmber to be X

the number is 12 less than it's square,

so X=12-X^2

=> X^2+X-12=0

=> (X+4)(X-3)=0

=>X= 3, or X=-4

in math we don't usually take negative numbers into account so your number would be 3

Danny wants to improve his technique for punting the football, so he devises an experiment to help. He goes to the field with 5
Triss [41]

Answer should be (A)

This is because the variation factors from one day to another may significantly  influence the distances the football goes. Among these factors are: the weather and Danny's condition. For example: wind strength, wind direction, any rain influences the skid, etc. Condition example could be: Danny is more tired on one of the days and can't kick as strong.

The other choices do not relate to variability.

Find the ARE of the figure
Tresset [83]
First, break up the shapes into parts. The first one you see is 7 by 4 rectangle on the top.
A=l*w
A=7*4
A=28 for the rectangle, your not done
Now the triangle to the left
A=l*w/2
A=19*10/2
A=95
Now all you got left is the trapezoid, which area's formula is:
A=(b∧1+b∧2*h)/2
A=9+19*8/2
A=112.
Now you have the area for three of the figures, add them up:
112+95+28=235
So in total, the area of this figure is 235 cm^2
