Answer:
Step-by-step explanation:
f(x) = –(x – 3)2 + 9
= 3² - (x – 3)2 identity a²-b² = (a+b)(a - b) where : a =3 and b = x-3
= ( 3+x-3) (3-x+3)
f(x) = x( 6-x)
the perimeter is ; 2(x +6-x) =12
the maximum area of the rectangle is : f(3) = 9 m²

Answer:
$2.59
Step-by-step explanation:
Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...
b +5m = 16.24
3b +2m = 15.05
Subtracting the second equation from 3 times the first, we have ...
3(b +5m) -(3b +2m) = 3(16.24) -(15.05)
13m = 33.67 . . . . . . simplify
m = 2.59 . . . . . . . . . divide by 13
The cost of a milkshake is $2.59.
