6.25 is probably the answer
Answer:
A) A = W(W + 4)
B) Length = 7 ft
Width = 3 ft
Step-by-step explanation:
A) Let the length and width of the rectangular rug be L and W respectively.
We are told that the rug is 4 feet longer than it is wide. Thus;
L = (W + 4)
Also we are told that the area is 21 ft²
Now, formula for area of a rectangle is;
A = LW.
Thus;
A = W(W + 4)
21 = W(W + 4)
B) 21 = W² + 4W
W² + 4W - 21 = 0
Using quadratic formula to find the roots, we arrive at W = 3 ft.
Thus, L = 3 + 4 = 7 ft
Answer:
64/27
Step-by-step explanation:
(4/3)^3=(4/3)*(4/3)*(4/3)=64/27
Answer:
Step-by-step explanation:
each page requires 2 Kb.
The USB drive will take 4 * 10^6 Kg
So 4 * 10^6 kb / 2 kb = 2 * 10^6 pages.
Amazing. I don't think this is an exaggeration. It looks just about the way things are.
The answer correct answer is 80.5
