Rectangle's perimeter formula is p=2(length+width)
2(9x+8x)=68
17x=34
x=2
length is 9(2)=18 feet
width is 8(2)=16feet
Answer:-2
Step-by-step explanation:
(n + 3) 5 = 3 x 1 - n
distribute so 5n + 15= 3 - n
subtract three from both sides
5n - 12 = -n
subtract 5n from both sides
12 = −6n
Divide both sides by -6
n=-2
Answer:
m= -9
Step-by-step explanation:

subtract 17 from both sides
(17-17) + m = 8-17 = -9
m= -9 check answer by replacing m with -9
17 + (-9)= 8
