Answer:
Step-by-step explanation:
P = 2(L + W)
P = 56
L = 12
now sub...we are looking for w
56 = 2(12 + W)
56 = 24 + 2W
56 - 24 = 2W
32 = 2W
32/2 = W
16 = W <==== the width is 16 inches
check...
P = 2(L + W)
56 = 2(12 + 16)
56 = 2(28)
56 = 56 (correct)
326/1000
AND
0.3260

Answer:
Q2) x=12
Q3) 66=29
Step-by-step explanation:
Q2) 7x−11=73
Step 1: Add 11 to both sides.
7x−11+11=73+11
7x=84
Step 2: Divide both sides by 7.
7x/7=84/7
x=12
Question 3:
Subtract 6 from 72
66 = 29
