-9n plus 9n is zero 3-8 is -5
Answer:
x + 8 + 12 + 11 = 43
Step-by-step explanation:
The perimeter is the length of the 4 sections of fencing.
If x represents the fourth section and the perimeter is 43, then
x + 8 + 12 + 11 = 43, that is
x + 31 = 43 ( subtract 31 from both sides )
x = 12
The length of the fourth section is 12 ft
Answer:
its obviously the property of zero as an exponent
Step-by-step explanation:
2/3y-4=x
2/3y*3/2=(x+4)*3/2
y=1.5x+6
