K = s + 4
k + s = 26
s + 4 = 26 
Subtract 4 from both sides of the equation.
s = 22

Answer: A. 
Step-by-step explanation:
To answer this, you must first understand what fractional exponents mean. 
An exponent of 1 is simply the base itself. 7^1 = 7. 
An exponent of 2 is squaring the base: 7^2 = 49. 
An exponent of 1/2 is taking the square root of the base: 7^(1/2) = sq root of 7
Therefore, an exponent of 1/3 is taking the cube root of the base. 
In this case, the base is 2.03 * t. 
Therefore, this can be represented as the cube root of the product of 2.03 and the age of the mammal, so the answer is A. 
 
        
             
        
        
        
Answer: The second option (160 cm)
Step-by-step explanation:
 1. You can obtain the perimeter of a quadrilateral by adding the lenghts of the sides.
 2. You know that the ratio of the side lengths is 3:3:5:8 and the perimeter is 380 centimeters.
 3. Therefore, you can write the following expression, where x is an integer:
 
 4. Solve for x:
 
 5. Therefore, the longest side is:
  (160 cm)
