The perimeter of a triangle is 27.1 feet. the sides of the triangle measure 9.8 feet, 10.9, and x feet

x = 6.4 feet.

Step-by-step explanation:

If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).

Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,

And its sides are 9.8 feet, 10.9 feet, and x feet.

Therefore, 27.1 = ( 9.8 + 10.9 + x )

⇒ 27.1 = 20.7 + x

⇒ x = 6.4 feet (Answer)

Part A: Total cost = 10 + 4s

Part B: Solving for s = 2

10 + 4 * 2 = US$ 18

Correct statement and question:

Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Admission to the zoo = US$ 10

Special exhibit cost (s) = US$ 4

2. Evaluate your expression when s = 2

Total cost = Cost of admission + (s) * Special exhibit cost

Total cost = 10 + (s) * 4

Total cost = 10 + 4s

3. Solving for s = 2

10 + 4s

10 + 4 * 2 = US$ 18
