Answer:
4x + 6 feet
Step-by-step explanation:
The deck is the shape of a rectangle
Hence, the perimeter of a rectangle is:
P = 2L + 2W
Where
L = Length = x feet
The width of the deck was 3 feet longer than the length.
W = Width = 3 + x feet
Hence:
Perimeter = 2(x ) + 2(3 + x)
Perimeter = 2x + 6 + 2x
Perimeter = 4x + 6 feet
Hence, the expression for the Perimeter of the deck is given as:
Answer: 45
Step-by-step explanation: j/9=5. Multiply both sides by 9: j=9×5=45. So j is 45.
I think it's 45.
46 + 89 = 135
adding all the angles of a triangle will always equal 180.
180 - 135 = 45
the last angle is 45.
