Use the simple perimeter formula.
P = 2L + 2W
P = 2(9) + 2(5)
P = 19 + 10
P = 29ft
Therefore 29ft of fencing will be needed.
Its DBC, cause two is in that point so you just find the answer choice with those three letters in the right order.
You factor the numerator and denominator and cancel the common factors. So maybe that should help you
2(x+1)+3x=37
simplifythe left side:
2x +2 +3x = 37
Combine like terms:
5x +2 = 37
Subtract 2 from both sides:
5x = 35
Divide both sides by 5:
x = 7
This is the answer if your question
