The length of the sides of a triangle are in the ratio 3:5:7. The difference between the longest side and the shortest side is 24cm. What is the perimeter of the triangle?​

P = 90 cm

Step-by-step explanation:

Let the sides of a triangle are 3x,5x and 7x.

The difference between the longest side and the shortest side is 24cm i.e.

7x-3x = 24

4x = 24

x = 6

Sides are :

3x = 3(6) = 18 cm

5x = 5(6) = 30 cm

7x = 7(6) = 42 cm

Perimeter = sum of  all sides

P = 18+30+42

P= 90 cm

Hence, the perimeter of the triangle is equal to 90 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
