All you have to do is divide how much he earned in all by the lawns he's mowed. And it comes out to be $15.25. That's how much he made each lawn. :)
Answer: =12.5h−25
Step-by-step explanation:
<u>Answer</u>
+2 and -2
<u>Explanation</u>
x^2-4=0 Is a quadrilateral expression. we can solve it using complete square method.
x²-4=0
x² - 4 + 4 = 0 + 4
x² = 4
x = √4 or x = - √4
= +2 = -2
This is an imaginary number = sqrt105 * i = 10i ro nearest integer
nCp = n! / (p!)*(n-p)!
so 12C8 = 12! / (8!)*(4!)
= 11880 / 24
= 495
ans is C
