The perimeter of the triangle below is 6a+2b-5 units. write an expression to represent the length in units, of the missing side of the triangle. me and show your work i am dyign

3a + 5b - 2

Step-by-step explanation:

The perimeter is the sum of all 3 sides of the triangle.

To find the missing side (x ) sum the 2 known sides and subtract from the perimeter.

x = 6a + 2b - 5 - (2a + 6b - 6 + a - 9b + 3 ) ← simplify parenthesis

  = 6a + 2b - 5 - (3a - 3b - 3 ) ← distribute by - 1

  = 6a + 2b - 5 - 3a + 3b + 3 ← collect like terms

  = 3a + 5b - 2 ← length of missing side

17 1/3

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
