Question

??????????? Help me I dont know

Answer 1

Answer:

c

Step-by-step explanation:

1. We can asume that a = 2, b = 4. Then solve and find which option matches with the answer.

2. Equation itself plugged in with a = 2, and b = 4. 2^2 + 2 x 2 x 4 + 4^2 = 36 / (2 + 4)^3

3. 36 / 216 = 1/6

Find any option that matches your answer and plug in a for 2 and b for 4.

a. a + b = 2 + 4 = 6 - No doesn’t match 1/6

b. a^2 + b^2 = 2^2 + 4^2 = 4 + 16 = 20 - No doesn’t match 1/6

c. 1 / a + b = 1 / 2 + 4 = 1/6 - Yes does match 1/6

d. 1 / (a + b)^2 = 1 / (2 + 4)^2 = 1/36 - No doesn’t match 1/6
