The perimeter of a triangle is the sum of the lengths of the three sides.
If the three expressions in the question are in fact the lengths of the
three sides, then the perimeter is their sum.
(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w
2x+2y
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
6x-2y
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
Suppose the length is y yards, then the perimeter is 2x + 2y = 6x + 6 yards so that 2y = 4x + 6 or y = 2x + 3 yards.
X + ( 2Y - 2X - Y ) is equal to Y - X
In its simplest form: 2y -5x
the answer to this problem is -2x^2y^2
It is an expression of terms that can be simplified to: x+2y+2
-4(7x-3y-z)-(-6)(9x-z+2)
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
