Answer:
w =4 ft and l =10 ft
Step-by-step explanation:
Let w = width
l = 2w+2
A = l*w
A = (2w+2)(w)
40 = (2w+2) w
Distribute
40 = 2w^2 +2w
Subtract 40
0 = 2w^2 +2w - 40
Dividing each side by 2
0 = w^2 +w -20
Factor
0 = (w+5) (w-4)
Using the zero product property
w+5 =0 w-4=0
w= -5 w=4
Since we cant have a negative length
w=4
l = 2w+2 = 2(4)+2 = 8+2 =10
I think you are missing information to solve this problem. Should there me an image attached to this question.
Either way, to solve for the label, the label would most likely me a rectangle when laid flat.
It's dimensions would be length x height.
Where height is most likely "h"
and
length is most likely the circumference (2πr)
Thus the possible answers are either:
B or C
I can't answer it until I see an image when more detail.
Hope this helps!
11/12* (1/6)
= 11/72.
The final answer is 11/72~
Answer:
143
Step-by-step explanation:
x-31=112
Add 31 to both sides,
x - 31 = 112
+31 +31
-31 and +31, cancel out so we're left with...
x = 143
