Step-by-step explanation:
Answer:
Length = 20feet
Width = 10feet
Step-by-step explanation:
Area of a rectangle = LW
Perimeter P= 2(L+W)
L is the length
W is the width
If the length of a rectangle is twice as long as the width, then;
L = 2W
Substitute into the foemula
A = (2W)W
A= 2W²
If the area is 200ft², then;
200 = 2W²
100 = W²
W = √100
W = 10ft
Since L = 2W
L = 2(10)
L = 20ft
Hence the length of the rectangle is 20feet and the Width is 10feet
-18
1) Distribute the -6 to the parentheses
-4 - (6*7) - (-6*3)
2) Simplify
-4 - 42 + 18
-18
"Betsy gets her hair cut every 28 days and Mary gets hers every 35 days"
Find the least common multiple of 28 and 35.
28 = 2²×7
35 = 5×7
LCM(28, 35) = 2²×5×7
= 140
