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)
Answer:

-----> equation D
step 1
Substitute equation D in equation C and solve for b




step 2
Find the value of GH
substitute equation B and equation D in equation A


substitute the value of b

Answer:

Step-by-step explanation:
Given:

Distribute to remove parentheses:

For simplification and clarity, reduce all mixed numbers to simplified common fractions:

Combine like terms:

Add 6/5 to both sides, then add 9/5x to both sides:

Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):
