Answer:
52 measures
Step-by-step explanation:
Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...
(108 -s) -(s) = 4
108 -2s = 4 . . . .collect terms
54 -s = 2 . . . . divide by 2
52 = s . . . . . add s-2
Grace's second song is 52 measures long.
Let the width of the room be = x
Length of the room = 3x, Since it is three times as wide
Perimeter = 80m
Perimeter = 2*(L + W) = 2*(3x + x) = 80
2*(3x + x) = 80
2*(4x) = 80
8x = 80 Divide both sides by 8
x = 80/8
x = 10, But length = 3x, = 3*10 = 30
Length = 30m
You are correct because the elapsed time was the shortest
hope this helps!
Answer: 8x^2° + 52x° + 27°
Using the knowledge i know i think this is the right answer
