SA=2H(L+W)+LW for open box
20=2H(4+W)+4(W)
distribute
20=8H+2WH+4W
divide both sides by 2
10=4H+WH+2W
solve for 1 variable, pick W
10-4H=WH+2W
10-4H=W(H+2)
(10-4H)/(H+2)=W
V=LWH
subsitute 4 for V, subsitute H for H and (10-4H)/(H+2) for W
V=(4)(H)(10-4H)/(H+2)
V=(40H-16H²)/(H+2)
find max value
take deritivitive of this thing
V'=-16(H²+4H-5)/((H+2)²)
using sign chart
sign changes from positive to negative at H=1
so at H=1
find W
W=(10-4H)/(H+2)
W=2
the dimeionts are
length=4ft
width=2ft
height=1ft
(the volume is 8 cubic feet)
Answer:the answer is 9,6
Step-by-step explanation:
I JUST TOOK THE QUIZ
You do 96 divide by 2 which is 48
your answer is 48
<span>they win 48 times
hope i helped!!</span>
When you take the absolute value of this equation, the answer should actually be 3.
You should solve the what’s inside first. If the answer is negative, then the absolute value will make it positive.
For example
|1-5|=|-4|=4
The difference between 5 and 2 1/5
5 - 2 1/5
borrow from the 5
4 5/5 - 2 1/5
2 4/5
Answer: 2 4/5
