The answer is 9. 5625 / 625 = 9
This means that 5625 square feet of lawn would provide the daily supplies of oxygen for 9 people
(-4)^2
A negative base raised to an even power gives us a positive so
4^2
4x4=16
105 - 75 = 30 That should do it.
Slope intercept form of a line is y=mx+b where m= slope and b=y-intercept.
So, we need to convert the given equation in this form. For that simply solve the equation for y.

Subtract 5x from each sides.
Multiply each sides by -1.
So, slope intercept frm is 
First, you need to find the total amount of games played by adding 11 and 9

Now you have to divide 11 by 20. If you wanted to find the percent of games lost, you would divide 9 by 20.

answer: 55%
