Length = width +6
L * (L - 6) = 135
L^2 - 6L = 135
L^2 - 6L -135 = 0
Length = 15
Width = 9
Answer:
5.79 feet
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
Third piece = z
Sac had a rope that was 15 feet long.
x + y + z = 15
He cut it into three pieces.
The first piece was 3.57 feet longer than the second piece.
x = 3.57 + y
The third piece was 2.97 feet longer than the second piece.
z = 2.97 + y
How long was the third piece of rope?
x + y + z = 15
3.57 + y + y + 2.97 + y = 15
3y + 6.54 = 15
3y = 15 - 6.54
3y = 8.46
y = 8.46/3
y = 2.82 feet
Therefore, the length of the third piece z = 2.97 + y
z = 2.82 + 2.97
z = 5.79 feet
Answer:
I think the first one is 18 and I think the second one is the 3rd one
Hello,
Converting 90 in to yd, we have:
90in * 1ft/12in * 1yd/3ft = 2.5 yd
Next,
Since A of a rectangle is b*h,
A = 2.5yd * 3yd = 7.5 yd ^2.
Good luck to you!
