Step-by-step explanation:
V=Lhw R=$/ft³
Vv=10.5(6)(6)
Vv=378 ft³
Rv=94.5/378
Rv= 25¢ per ft³
Vs=12(8)6.75
Vs=648 ft³
Rs=162/648
Rs=25¢ per ft³
------
Vl=20(8.75)8.5
Vl=1487.5 ft³
1487.5=648n
2.295=n

Answer:
The solutions are 3 and -5
Step-by-step explanation:
x+3=x^2+3x-12
x^2+2x-15
=(x-3)(x+5)
ANSWER
(-2,-1)
(3,14)
EXPLANATION
The given system is


or

Equate both of them:

This implies that,


x=-2 or x=3
When x=-2, y=y=3(-2)+5=-1
(-2,-1) is a solution.
When x=3 , y=3(3)+5=14
(3,14) is also a solution.
Answer: The discount is $30, making the sale price $270.
