The measures of the 3 sides of a triangle can be represented by algebraic expressions x, 3x-1, and 4x＋2.the perimeter of the triangle is 81inches. what are the lengths of the sides of the triangle?

X + 3x - 1 + 4x + 2 = 81
(add all the like terms)
8x + 1 = 81
8x = 81 - 1
8x = 80
x = 80/8
x = 10

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !

The answers 5 so there’s the you need trust me it’s right
