P=x+38
add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10
set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x
then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46
sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11
Answer:
16= 7 &
17= 9
Step-by-step explanation:
P = 2(L + W)
P = 228
L = 2W + 6
228 = 2(2W + 6 + W)
228 = 2(3W + 6)
228 = 6W + 12
228 - 12 = 6W
216 = 6W
216/6 = W
36 = W <=== width is 36 ft
L = 2W + 6
L = 2(36) + 6
L = 72 + 6
L = 78 <=== length is 78 ft
Answer:
12x + 8 = 12 x 6 + 8 = 80
8x-3 = 8 x 6 - 3 = 44
Step-by-step explanation:
(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)
(8+55-3) + (12x + 8x) = 180( group the variables)
(60) + (20x) = 180
20x = 180 - 60
20x = 120
x = 120/20 = 6
x=6
Step 1
