325.5*.15 = 48.825
325.5 - 48.825 = 276.68 (rounded)
You need to subtract the two cutouts on each side, so the side of the box would be 24- 2x. X would then become the height of the box once folded.
The volume is found by multiplying the 4 dimensions:
The volume becomes x(24-2x)^2
Now take the derivative of the formula to solve for x
Dv/dx= (24-2x)^2 + x^2(24-2x)*-2
= 24-2x(24-2x-4x)=0
X =12 or 4
24-2x = 24-2(4) = 24-8=16
Volume = 16 x 16 x 4 = 1024 cubic inches.
W² - 49 = 0
w² - 7² = -
(w-7)(w+7)=0
w -7=0 , or w + 7 =0
w=-7, w=7
Answer: -7, 7.
1st number = x
2nd number = y
2x + y = 26
-
x + y = 10
x = 16
26 - (2 x 16) = -6
10 - 16 = -6
Number 1 is 16
Number 2 is -6
B since 11+11=22 and 3/7+4/7=1, 22+1=23
