Answer:
12−2
Step-by-step explanation:
Simplify,
(11+3)+(−5)
11+3+−5
Subtract,
11+3+−5
11−2+
Combine like terms,
11−2+
12−2
Since we can't go any further, the solution is,
12−2
Answer:
The porch is 17 ft by 17 ft
Step-by-step explanation:
The perimeter of a square is
P = 4s where s is the side length
P = 4( 3x+2)
P = 12x+8
We know P = 14x-2
14x-2 = 12x+8
Subtract 12x from each side
14x-2 -12x = 12x+8-12x
2x -2 = 8
Add 2 to each side
2x-2 +2 = 8+2
2x= 10
Divide by 2
2x/2 = 10/2
x = 5
The side is 3x+2
3*5+2
15+2
17
The porch is 17 ft by 17 ft
