Answer:
9(3+5)
I'm not sure if this'll be right, but here goes. When there is a number before ( ) without a symbol in between, it means that you have to multiply the number (which in this case is 9) with each of the numbers in ( ) (in this case 3 and 5)
1) 9×3=27
2) 9×5=45
And that way you get the answer 27+45
Sorry if this was a bit confusing, I'm not actually English, so I didn't exactly know how to explain it :)

Answer:
y = 9
Step-by-step explanation:
Given y is directly proportional to (x - 1)² then the equation relating them is
y = k(x - 1)² ← k is the constant of proportionality
To find k use the condition x = 5 when y = 4
k = = = = , thus
y = (x - 1)² ← equation of proportion
When x = 7, then
y = × 6² = × 36 = 9
Yeah the other guy is right. Please like I need the points !!!! :((
