Answer:
D. ÷ 3
Step-by-step explanation:
We can use any numbers for x to see what would happen to y:
If x was 5, y would be 1 (because 5 ÷ 5 = 1). Now, if we tripled x and made it 15 (5 × 3 = 15), y would be 1/3 (because 5 ÷ 15 = 1/3).
This means that the value of y divides by 3, option D
Hope this helps!
Answer:
Numerator 2b^2 + 2a^2
Denominator (b-a)(b+a)^2
2b / (b+a)^2 + 2a / (b-a)(b+a)
2b (b-a) + 2a (b + a) / (b-a) * (b+a)^2
2b^2 - 2ab + 2ab + 2a^2 / (b-a)(b+a)^2
2b^2 + 2a^2 / (b-a) * (b+a)^2
