the perimeter of an equilateral triangle is 14.4 cm. Find out the length of the side of that triangle in decimal fraction. (step by step)

43.2 is the correct answer happy

Step-by-step explanation:

An equilateral triangle has three equal sides.

∴ the perimeter of an equilateral triangle = 3 × side

Since the perimeter = 14.4 cm

⇒      14.4 cm = 3 × side                   [divide through by 3]

⇒           side = 14.4 cm ÷ 3              [simplify]

             side = 4.8 cm

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
