The length of each of the two congruent sides of nan isosceles triangke is 4x+2. The length of the of third side is 2x. The perimeter is 29 centimeters. Write an equation that could be used to find to find the value of x.
Solve for x and find the length of all three sides.

Value of x is 2.5 and the sides are 5 cm, 12 cm and 12 cm.

Step-by-step explanation:

Perimeter of a triangle = Sum of its sides

⇒ 29 = 2(4x  + 2) + 2x = 8x + 4 + 2x = 10x + 4

⇒ 29 = 10x + 4

⇒ 10x - 25 = 0 is the equation

⇒ 10x = 25

⇒ x = 25/10 = 2.5

2x = 2 × 2.5 = 5cm

4x + 2 = 4 × 2.5 + 2 = 10 + 2 = 12 cm

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
