The answer is 8. The two negatives cancel each other out.
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
1. Work out difference between the two numbers you are comparing and divide the decreased number by using the original number.
2. Multiply by 100
3. If it is negative, then this will indicate that it is a percentage increase. However, if it is positive, it is the percentage decrease,
I hope this helped.
