Step-by-step explanation:
W = (2L -57)
P = 2×(L+W)
198 = 2× (L + 2L -57)
198 = 2× (3L - 57)
3L-57 = 198/2
3L-57 = 99
3L = 99+57
3L = 156
L = 156/3 = 52
W = 2(52) -57 = 104-57 = 47
so, the length = 52 ft
and the width = 47 ft
No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
Answer:
All numbers from 7 and up (x is greater than or equal to 7)
Step-by-step explanation:
|7-7| =7-7
0=0
|8-7|=8-7
1=1
BUT
|6-7| =/= 6-7
1 =/= -1
4+5=9
24 divided by 9=2.6
2.6x4=10.4
2.6x5=13
= 10.4:13
I hope thats right
sorry if not but i think it is
<span>P=34</span> inches<span>
a= left side=6 inches</span>
b= top side
P=2a+2b<span>
<span>P=34=2*6+2b
34=12+2b
b=11</span></span>
the length of the top side is 11 inches
