perimeter of a triangle ABC
Perimeter of a Triangle
= AB + BC + CA
= 10cm + 8cm + 12cm,
(add the length of each side of the triangle).
= 30cm
Perimeter of the triangle = Sum of the sides.
Number one is 13.2 now hold up while I do the rest

Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (-
, 0) and (x₂, y₂ ) = (0,
)
m =
=
=
and c =
, then
y =
x +
( multiply through by 4 to clear the fractions )
4y = 2x + 3 ( subtract 4y from both sides )
0 = 2x - 4y + 3 , that is
2x - 4y + 3 = 0 ← equation of line
