Answer:
18 feet in 20 minutes.
Step-by-step explanation:
1. squaring
2. four triangles and the square with side length "c"
3. big square (side length: a+b)
17-4x = 1-4x+12-2x
17-4x = 13-6x | +4x
17 = 13-2x | -13
4 = -2x | :(-2)
-2 = x
Y+4
plug in 3.6 for y
3.6+4
will give you the result of 7.6
20 + 17y = -6 + 15y
First, regroup your terms.
Second, take away '15y' from each side.
Third, subtract '17y - 15y' to get '2y'.
Fourth, take away '20' from both sides.
Fifth, simplify '-6 - 20' to get '-26'.
Sixth, divide both sides by '2'.
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.

Answer:
y = -13
