Answer:6-8^10=?
Step-by-step explanation:
Answer:
Length is 14
Width is 6
Step-by-step explanation:
Length = 2W + 2
Width = W
Perimeter is twice the length + twice the width
P = 40 = 2(2W+2) + 2W first simplify
40 = 4W + 4 + 2W now combine terms
40 = 6W + 4 and subtract 4 from both sides
36 = 6W
Width W = 6
Length = 2W + 2 = 12 + 2 = 14
Assuming the other is equal to x, this would be a 30-60-90 triangle. This is because those angles must add to 90 degrees and one must be 2 times the second.
It must be a and c, as these are the only two with four closed sides
1 pound is .45 kilograms
120 pounds is 54.4311 killograms
