The perimeter of the given equilateral triangle is 42 cm find s if it's side length is (3s+2) cm

14cm

Step-by-step explanation:

Given parameters:

        perimeter of the triangle  = 42cm

        length of side = (3s + 2)cm

Unknown:

Find the length of each side = ?

Solution:

The perimeter of a body is the sum of all its sides.

 In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;

     (3s + 2) + (3s + 2) + (3s + 2)  = 42

            9s + 6 = 42

            9s  = 42 - 6

            9s = 36

              s  = 4;

The length of its sides = 3s + 2

                                     = 3(4) + 2

                                     = 12 + 2

                                     = 14cm

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
