1. A triangle has the following lengths-
Side 1: 4x+1,
Side 2: 6x - 5, and
Side 3: x + 1.
Its perimeter is 41 cm.

Answer:

Side 1: 17cm. Side 2: 19cm. Side 3: 5cm.

Step-by-step explanation:

Equation:

  1. (4x+1)+(6x-5)+(x+1)=41
  2. Remove parenthesis, 4x+1+6x-5+x+1=41
  3. Combine like terms, 11x-3=41
  4. Add, 11x=44
  5. Divide, x=4

Now, find the side lengths:

  1. 4(4)+1=16+1=17
  2. 6(4)-5=24-5=19
  3. 1(4)+1=4+1=5

Double check:

  1. 15+19+5=41
