Answer:
The length is 14 m.
Step-by-step explanation:
length = L
width = W
perimeter = P
"The perimeter of a rectangle is twice the sum of its length and its width."
P = 2(L + W)
"The perimeter is 40 meters"
40 = 2(L + W)
"and its length is 2 meters more than twice its width."
L = 2W + 2
Replace L with 2W + 2 in equation 40 = 2(L + W):
40 = 2(2W + 2 + W)
40 = 2(3W + 2)
20 = 3W + 2
3W = 18
W = 6
The width is 6 meters.
L = 2W + 2 = 2(6 m) + 2 m = 12 m + 2 m = 14 m
Answer: The length is 14 m.
Ok so there are 8 min of commercials and if each commercial is .25 minutes. what I did was 8 × 60 to get how many seconds there were. which = 480 and then I did .25 min × 60 and got 15 so I subtracted 15 from 480 and got 7.75
but it says how many commercials so you have to round to the full commercial and you get 8
so I think the answer is 8 or 7.75.
