PLEASE HELP

1) A triangle has two sides of length 3m-4 and one side of length m. if the total perimeter is 76 inches, how long is side m?

2) A square has 4 sides of length 4x+5 if the total perimeter of 200 find the value of x

m is 12 and x is 11.25

Step-by-step explanation:

Find side m of the triangle. Given the sides are 3m - 4, 3m - 4 and m. Perimeter = 76 inches

⇒ m + 2(3m - 4) = 76 (Since perimeter of a triangle = sum of its sides)

⇒ m + 6m - 8 = 76

⇒ 7m = 84

⇒ m = 12 inches

Find x. Given side of the square is 4x + 5 and perimeter = 200

⇒ 4 × (4x + 5) = 200 (Since perimeter of a square = 4 × side)

⇒ 16x + 20 = 200

⇒ 16x = 180

⇒ x = 11.25
